IB/ehca: Returns an error on ib_copy_to_udata() failure
commit 5bdb0f02add5994b0bc17494f4726925ca5d6ba1 upstream.
In case of error when writing to userspace, function ehca_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().
