cifs: Make add_credits_and_wake_if() clear deducted credits

Make add_credits_and_wake_if() clear the amount of credits in the
cifs_credits struct after it has returned them to the overall counter.
This allows add_credits_and_wake_if() to be called multiple times during
the error handling and cleanup without accidentally returning the credits
again and again.

Note that the wake_up() in add_credits_and_wake_if() may also be
superfluous as ->add_credits() also does a wake on the request_q.
