MFC r268316:
Fix OFED startup order: All SYSINIT()'s and modules should be loaded
prior to starting "/sbin/init" which will run all the "/etc/rc.d/xxx"
scripts. Else there can be a race configuring the interfaces via
"/etc/rc.conf".

rename scheduler->swapper and SI_SUB_RUN_SCHEDULER->SI_SUB_LAST

Also directly call swapper() at the end of mi_startup instead of
relying on swapper being the last thing in sysinits order.

Rationale:

- "RUN_SCHEDULER" was misleading, scheduling already takes place at that stage
- "scheduler" was misleading, the function swaps in the swapped out processes
- another SYSINIT(SI_SUB_RUN_SCHEDULER, SI_ORDER_ANY) could never be
invoked depending on its relative order with scheduler; this was not obvious
and the bug actually used to exist
