mtd: cfi_cmdset_0001: silence spurious suspend warning on shutdown

cfi_intelext_reboot() puts each chip into FL_SHUTDOWN (array mode) via
the reboot notifier so the bootloader can read the flash on the next
boot. If pm_suspend then runs on the same chip during the shutdown
sequence, cfi_intelext_suspend() falls into the default branch and
prints:

  Flash device refused suspend due to active operation (state 20)

The chip is not active; it is already shut down. Treat FL_SHUTDOWN the
same as FL_PM_SUSPENDED in the suspend switch so nothing is done and
no warning is emitted.

Reproduced on every boot of the QEMU 'virt' arm64 machine, which
exposes two Intel-Sharp pflash chips.
