        src/sys/compat/linux/common: linux_sched.c

Log Message:
Remove unused variable p from linux_sys_clone()

After refactoring by <chs> in 2010 (r. 1.63) the p variable is no longer
used.

As noted by <Mateusz Guzik> its usage is also unsafe and might cause
use-after-free scenarios.

No functional change intended.
