selftests/resctrl: ksft_exit_skip() does not return

After commit f7d5bcd35d42 ("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 calls to ksft_exit_skip(), as __noreturn prevents
the compiler from warning that a caller of ksft_exit_skip() does not
return a value because the program will terminate upon calling these
functions.
