Pan Bian 8b2522eb44 drm/amdkfd: fix improper return value on error ...

[ Upstream commit 8bf793883da213864efc50c274d2b38ec0ca58b2 ]

In function kfd_wait_on_events(), when the call to copy_from_user()
fails, the value of return variable ret is 0. 0 indicates success, which
is inconsistent with the execution status. This patch fixes the bug by
assigning "-EFAULT" to ret when copy_from_user() returns an unexpected
value.
