Viacheslav Ovsiienko b53cd86965 net/mlx5: adjust inline setting for large Tx queue sizes 
The hardware may have limitations on maximal amount of
supported Tx descriptors building blocks (WQEBB). Application
requires the Tx queue must accept the specified amount of packets.
If inline data feature is engaged the packet may require more WQEBBs
and overall amount of blocks may exceed the hardware capabilities.
Application has to make a trade-off between Tx queue size and maximal
data inline size.

In case if the inline settings are not requested explicitly with
devarg keys the default values are used. This patch adjusts the
applied default values if large Tx queue size is requested and
default inline settings can not be satisfied due to hardware
limitations.

The explicitly requested inline setting may be aligned (enlarging
only) by configurations routines to provide better WQEBB filling,
this implicit alignment is the subject for adjustment either.

The warning message is emitted to the log if adjustment happens.
