[PATCH net] qed: Unlock on error in qed_vf_pf_acquire()

[Dan Carpenter]

My static checker complains that we're holding a mutex on this error
path.  Let's goto exit instead of returning directly.

Yuval, could you review this one a bit carefully and also check that my
Fixes tag is correct because I'm not certain.
