mpt2sas: move even handling of MPT2SAS_TURN_ON_FAULT_LED into process context
commit
3ace8e052be5293ebb3e00f819effccc64108a38 upstream.
Driver was a sending a SEP request during interrupt context which
required to go to sleep.
The fix is to rearrange the code so a fake event
MPT2SAS_TURN_ON_FAULT_LED is fired from interrupt context, then later
during the kernel worker threads processing, the SEP request is issued
to firmware.
