PATCH 1/1 IB/srpt: Suppress a compiler warning
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.
