[PATCH] IB/srp: remove forward declaration of srp_post_recv()

[Bart Van Assche <bvanassche-HInyCGIudOg@public.gmane.org>]

This patch removes the forward declaration of srp_post_recv() that was
introduced in the patch called "IB/srp: receive buffer handling robustness
improvement" by changing the order of the function definitions in ib_srp.c.
