The parsing of the reboot= cmdline has two major errors:

• a missing bound check can crash the system on reboot
• parsing of the cpu number only works if specified last

Fix both, along with a small code refactor.

v1->v2: As Petr suggested, don't force base 10 in simple_strtoul(), so hex values are accepted as well.
