Ross Zwisler 4557641b4c pmem: only set QUEUE_FLAG_DAX for fsdax mode ...

QUEUE_FLAG_DAX is an indication that a given block device supports
filesystem DAX and should not be set for PMEM namespaces which are in "raw"
mode.  These namespaces lack struct page and are prevented from
participating in filesystem DAX as of commit 569d0365f5 ("dax: require
'struct page' by default for filesystem dax").
