[PATCH] IB/srpt: Suppress a compiler warning

[Bart Van Assche <bart.vanassche-XdAiOPVOjttBDgjK7y7TUQ@public.gmane.org>]

Remove a BUG_ON(!ch) statement because it is superfluous - if
the ch pointer would be NULL then the assignment in the first
line of srpt_map_sg_to_ib_sge() would trigger a kernel oops anyway.

This patch suppresses the following compiler warning:

Possible null pointer dereference: ch - otherwise it is redundant to
check it against null.
