media: s2255: Remove unnecessary return statements from void functions

Browse Source 
Fix all 7 'WARNING: void function return statements are not generally
useful' issues reported by checkpatch.pl in s2255drv.c. Remove
trailing 'return;' statements that immediately precede the closing
brace in void functions.
