Slawomir Mrozowicz 6e15a19c62 net/i40e: fix unintended sign extension
Suspicious implicit sign extension: pf->fdir.match_counter_index
with type unsigned short (16 bits, unsigned) is promoted in
"pf->fdir.match_counter_index << 20" to type int (32 bits, signed),
then sign-extended to type unsigned long (64 bits, unsigned).
If "pf->fdir.match_counter_index << 20" is greater than 0x7FFFFFFF,
the upper bits of the result will all be 1.

To fix the issue explicitly cast pf->fdir.match_counter_index to uint32_t.

Coverity issue: 13315
