Dan Williams 43672fa642 dax: fix vma_is_fsdax() helper ...

commit 230f5a8969 upstream.

Gerd reports that ->i_mode may contain other bits besides S_IFCHR. Use
S_ISCHR() instead. Otherwise, get_user_pages_longterm() may fail on
device-dax instances when those are meant to be explicitly allowed.

Fixes: 2bb6d28370 ("mm: introduce get_user_pages_longterm")
