block: renumber QUEUE_FLAG_HW_WC

Browse Source 
[ Upstream commit 02d374f3418df577c850f0cd45c3da9245ead547 ]

For the QUEUE_FLAG_HW_WC to actually work, it needs to have a separate
number from QUEUE_FLAG_FUA, doh.

Fixes: 43c9835b144c ("block: don't allow enabling a cache on devices that don't support it")
