RDMA/srpt: fix function pointer cast warnings

[ Upstream commit eb5c7465 ]

clang-16 notices that srpt_qp_event() gets called through an incompatible
pointer here:

drivers/infiniband/ulp/srpt/ib_srpt.c:1815:5: error: cast from 'void (*)(struct ib_event *, struct srpt_rdma_ch *)' to 'void (*)(struct ib_event *, void *)' converts to incompatible function type [-Werror,-Wcast-function-type-strict]
 1815 |                 = (void(*)(struct ib_event *, void*))srpt_qp_event;

Change srpt_qp_event() to use the correct prototype and adjust the
argument inside of it.
