acpi: do not run resume/backout code when entering S0/S5 states
This change adds (possibly redundant) early check for invalid
state input parameter (including S0). Handling of S5 request
is reduced to simply calling shutdown_nice(). As a result
control flow of acpi_EnterSleepState is somewhat simplified
and resume/backout half of the function is not executed
for S5 (soft poweroff) request and invalid state requests.
Note: it seems that shutdown_nice may act as nop when initproc
is already initialized (to grab pid of 1), but init process is in
"pre-natal" state.
