Cairo always uses native byte order for rendering.
Hence if the byte order of the frame buffer differs from the byte order
of the CPU, the frame buffer contents need to be byteswapped twice: once
before rendering, to convert to native byte order, and a second time
after rendering, to restore the frame buffer format's byte order.
Note that byte swapping is not done for ARGB32 formats, as for these
formats, byte order only affects the order of the red, green, and blue
channels, which we do not care about here.

When specifying a frame buffer format like "RG16_BE" (big-endian RG16),

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.
