Paul Moore 6a9e261cbb selinux: don't sleep when CONFIG_SECURITY_SELINUX_CHECKREQPROT_VALUE is true 
Unfortunately commit 81200b0265b1 ("selinux: checkreqprot is
deprecated, add some ssleep() discomfort") added a five second sleep
during early kernel boot, e.g. start_kernel(), which could cause a
"scheduling while atomic" panic.  This patch fixes this problem by
moving the sleep out of checkreqprot_set() and into
sel_write_checkreqprot() so that we only sleep when the checkreqprot
setting is set during runtime, after the kernel has booted.  The
error message remains the same in both cases.

Fixes: 81200b0265b1 ("selinux: checkreqprot is deprecated, add some ssleep() discomfort")
