Currently the atomic request is only assigned after `set_property()` is
called, leaving `dev.req` in its uninitialized state causing
`drmModeAtomicAddProperty()` to return an error code, which is printed
as `"Success"` because `errno` is not set by `libdrm` (but it would have
been when non-atomic `drmModeObjectSetProperty()` called an IOCTL
immediately):
sony-akatsuki-row ~ $ modetest -M msm -a -w 81:ACTIVE:0
failed to set CRTC 81 property ACTIVE to 0: Success
Solve this by assigning a new atomic request object before calling
`set_property()`, when there are properties to set. Likewise, commit
these properties after `set_property()` even if there is no other
operation (setting modes or planes) specified.
Furthermore `drmModeObjectSetProperty()` is implemented in terms of
`DRM_IOCTL()` which already returns `-errno` when `ioctl()` returns
`-1`, so we should instead pass `ret` to `strerror()` and get an
accurate error string out of `drmModeAtomicAddProperty()` too.
