mtd: mtdoops: panic caused mtdoops to call mtdoops_erase function immediately
The panic function disables the local interrupts, preemption, and all
other processors. When the invoked mtdoops needs to erase a used page,
calling schedule_work() to do it will not work. Instead, just call
mtdoops_erase function immediately.
Tested:
~# echo c > /proc/sysrq-trigger
[ 171.654759] sysrq: Trigger a crash
[ 171.658325] Kernel panic - not syncing: sysrq triggered crash

[ 172.406423] mtdoops: not ready 34, 35 (erase immediately)
[ 172.432285] mtdoops: ready 34, 35
[ 172.435633] Rebooting in 10 seconds..
