msm: sde: Move SDE rotator timeout evtlog outside of spinlock

During an timeout event in the SDE rotator driver, a spinlock with IRQ
is disabled in order to capture the rotator hw status registers. If
during this time performs an evtlog timeout logging, a mutex_lock
within the logging sequence will cause a panic. We must and only should
perform the evtlog timeout logging after the spinlock is released.
