Johannes Thumshirn 2db4215f47 scsi: sd_zbc: Update write pointer offset cache 
Recent changes changed the completion of SCSI commands from Soft-IRQ
context to IRQ context. This triggers the following warning, when we're
completing writes to zoned block devices that go through the zone append
emulation:

Don't use spin_lock_bh() to protect the update of the write pointer offset
cache, but use spin_lock_irqsave() for it.
