net/mlx5: HWS, changed E2BIG error to a negative return code
Fixed all the 'E2BIG' returns in error flow of functions to
the negative '-E2BIG' as we are using negative error codes
everywhere in HWS code.
This also fixes the following smatch warnings:
"warn: was negative '-E2BIG' intended?"
Fixes: 74a778b4a63f ("net/mlx5: HWS, added definers handling")

Closes: https://lore.kernel.org/all/f8c77688-7d83-4937-baba-ac844dfe2e0b@stanley.mountain/
