Remove unnecessary variable "meta" in ice_flow_create and
ice_flow_validate, it should be defined when really needed:
its ice_parse_engine_create and ice_parse_engine_validate.
A meta data created by parser->parse_pattern_action should be
freed inside parser->engine->create.
During a validate operation, since parser->engine_>create will not
be invoked, it is unnecessary to create a meta during parser, so
NULL will passed to engine->parse_pattern_action and all parser's
parse_pattern_action need to be modified to handle meta = NULL
properly.
With above implementation, the patch also fixes a potential memory
leak in ice_parse_engine_validate, since meta may not be freed.
BTW, an engine without a create op should be regarded as a bug. So
use RTE_ASSERT to replace runtime engine->create == NULL check in
ice_parse_engine_create.

Commit 'dc36bd5dfdeb' mistakenly initializes ret as -rte_errno, then
return ret if ice_search_pattern_match_item fails, if rte_errno happens
to be 0 in this case, it would cause an unrecognized flow rule to be
marked as recognition success. Later, when the code tries to parse the
flow rule, a segmentation fault will occur due to null pointer
reference.

Currently, multiple rte_flow RSS rules may map to the same
hardware rule if a later rule is just for input set change or
symm turn on/off. So after one of the rules be destroyed, we will
get error ICE_ERR_DOES_NOT_EXIST when destroying any other rules.
The patch simply fixes this by ignoring this error. A more
sophisticated fix that remember the sequence and replay properly
will be provided in the future.

In ice_hash_create(), whatever the hash_function is, the
filter_ptr->symm is always 0 and when we destroy the flow, the
ice_rem_rss_cfg() is never carried out. So the destroy function never
works well. The patch fixes this issue and at the same time
distinguishes between simple_xor and symmetric_toeplitz.
To fix this issue, the patch adds a new structure to include a flag to
indicate if it is a simple_xor flow so that it's easier to remove the
config when destroying the flow. The patch also simplifies code
implementation logic in ice_hash_create().
