bcache: work around a __bitwise to bool conversion sparse warning

Browse Source 
Sparse is a bit dumb about bitwise operation on __bitwise types used
in boolean contexts.  Add a !! to explicitly propagate to boolean
without a warning.

Fixes: fcf865e357 ("block: convert features and flags to __bitwise types")
