Subject: [PATCH] bnx2x: fix wrong return from bnx2x_trylock_hw_lock

bnx2x_trylock_hw_lock() returns a bool :

true if succeeded to acquire the lock.
false in case of error.

-EINVAL is not an acceptable value, since its promoted to true.

Cosmetic patch, since compiler probably omits the code anyway.
