Abhijeet Dharmapurikar fa3a6d5572 power: wakelock: reset wakelock checked early ...

Currently we reset msm_suspend_check_done in resume_noirq and set it
in the suspend_noirq stage right after the wakelock checks are done.

An issue is discovered recently that a wakelock can be held much earlier
in the resume sequence - a tasklet was scheduled right in the arch specifc
resume path, and this tasklet was run as soon as local interrupt was
enabled (the I bit in the CPSR for arm processors).  The tasklet endedup
grabbing a wakelock thus causing a BUG.

To avoid this situation reset msm_suspend_check_done before enabling local
interrupts using the syscore ops.
