usb: gadget: ffs: ffs_aio_cancel(): Save/restore IRQ flags
[ Upstream commit 43d565727a3a6fd24e37c7c2116475106af71806 ]
ffs_aio_cancel() can be called from both interrupt and thread context. Make
sure that the current IRQ state is saved and restored by using
spin_{un,}lock_irq{save,restore}().
Otherwise undefined behavior might occur.
