RDMA: Fix double-free in srq creation error flow
The cited commit introduced a double-free of the srq buffer in the error
flow of procedure __uverbs_create_xsrq().
The problem is that ib_destroy_srq_user() called in the error flow also
frees the srq buffer.
Thus, if uverbs_response() fails in __uverbs_create_srq(), the srq buffer
will be freed twice.
