IB/mthca: Return an error on ib_copy_to_udata() failure
commit 08e74c4b00c30c232d535ff368554959403d0432 upstream.
In case of error when writing to userspace, the function mthca_create_cq()
does not set an error code before following its error path.
This patch sets the error code to -EFAULT when ib_copy_to_udata() fails.
This was caught when using spatch (aka. coccinelle)
to rewrite call to ib_copy_{from,to}_udata().
