RDMA/uverbs: Prevent integer overflow issue
In the expression "cmd.wqe_size * cmd.wr_count", both variables are u32
values that come from the user so the multiplication can lead to integer
wrapping. Then we pass the result to uverbs_request_next_ptr() which also
could potentially wrap. The "cmd.sge_count * sizeof(struct ib_uverbs_sge)"
multiplication can also overflow on 32bit systems although it's fine on
64bit systems.
This patch does two things. First, I've re-arranged the condition in
uverbs_request_next_ptr() so that the use controlled variable "len" is on
one side of the comparison by itself without any math. Then I've modified
all the callers to use size_mul() for the multiplications.
