Conform to Linux kernel coding style.
Reported by checkpatch:
WARNING: else is not generally useful after a break or return
Expressions under 'else' branch in function 'dm_crtc_get_scanoutpos' are
executed whenever the expression in 'if' is False. Otherwise, return
from function occurs. Therefore, there is no need in 'else', and it has
been removed.
