After commit f7d5bcd35d ("selftests: kselftest: Mark functions that
unconditionally call exit() as __noreturn"), ksft_exit_...() functions
are marked as __noreturn, which means the return type should not be
'int' but 'void' because they are not returning anything (and never were
since exit() has always been called).
To facilitate updating the return type of these functions, remove
'return' before the call to ksft_exit_pass(), as __noreturn prevents the
compiler from warning that a caller of ksft_exit_pass() does not return
a value because the program will terminate upon calling these functions
(which is what the comment alluded to as well).
