[RFC net-next 05/15] HACK: net: lora: Deal with .poll_mask in 4.18-rc2

["Andreas Färber" <afaerber@suse.de>]

linux-next and 4.18-rc2 both identify as LINUX_VERSION(4,18,0), but
commit a11e1d432b51f63ba698d044441284a661f01144 (Revert changes to
convert to ->poll_mask() and aio IOCB_CMD_POLL) reverted .poll_mask
to .poll again.
