net/mlx5: Fix bit-wise and with zero

Browse Source 
[ Upstream commit 82c3ba31c370b6001cbf90689e98da1fb6f26aef ]

The bit-wise and of the action field with MLX5_ACCEL_ESP_ACTION_DECRYPT
is incorrect as MLX5_ACCEL_ESP_ACTION_DECRYPT is zero and not intended
to be a bit-flag. Fix this by using the == operator as was originally
intended.

Addresses-Coverity: ("Logically dead code")
Fixes: 7dfee4b1d79e ("net/mlx5: IPsec, Refactor SA handle creation and destruction")
