KVM: selftests: Add missing "break" in rseq_test's param parsing

In commit 0297cdc12a87 ("KVM: selftests: Add option to rseq test to
override /dev/cpu_dma_latency"), a 'break' is missed before the option
'l' in the argument parsing loop, which leads to an unexpected core
dump in atoi_paranoid(). It tries to get the latency from non-existent
argument.

  host$ ./rseq_test -u
  Random seed: 0x6b8b4567
  Segmentation fault (core dumped)

Add a 'break' before the option 'l' in the argument parsing loop to avoid
the unexpected core dump.
