[MTD] [NOR] fix ctrl-alt-del can't reboot for intel flash bug

When we press ctrl-alt-del,kernel_restart_prepare will invoke 
cfi_intelext_reboot which will set flash to read array mode, but later 
when device_shutdown is invoked which may put current work queue to 
sleep and other process may be scheduled to running and programming 
flash in not FL_READY mode again. So we can't boot up if this flash is 
used for bootloader.
