drm: msm: Fix return type of dsi_mgr_connector_mode_valid for kCFI
I was hitting kCFI crashes when building with clang, and after some digging finally narrowed it down to the dsi_mgr_connector_mode_valid() function being implemented as returning an int, instead of an enum drm_mode_status. This patch fixes it, and appeases the opaque word of the kCFI gods (seriously, clang inlining everything makes the kCFI backtraces only really rough estimates of where things went wrong). Thanks as always to Sami for his help narrowing this down.
