bcache: Make sure to pass GFP_WAIT to mempool_alloc()

commit bcf090e0040e30f8409e6a535a01e6473afb096f upstream.

this was very wrong - mempool_alloc() only guarantees success with GFP_WAIT.
bcache uses GFP_NOWAIT in various other places where we have a fallback,
circuits must've gotten crossed when writing this code or something.
