A missing break in kms_tests leads to kselftest hang when the parameter -s
is used.

In current code flow because of missing break in -s, -t parses args
spilled from -s and as -t accepts only valid values as 0,1 so any arg in
-s >1 or <0, gets in ksm_test failure

This went undetected since, before the addition of option -t, the next
case -M would immediately break out of the switch statement but that is no
longer the case

Add the missing break statement.
