fuse: handle extent map files in fuse_passthrough_fadvise()
This addresses a collision between the pending backing_file fadvise
patch and the new extent-mapping code for famfs (which falls into the
passthrough bucket.
A file opened with FOPEN_PASSTHROUGH on an extent map backing has no
backing file: fuse_passthrough_open() returns before setting
ff->passthrough and ff->cred. fuse_file_fadvise() routes every
FOPEN_PASSTHROUGH file to fuse_passthrough_fadvise(), which installed
the NULL ff->cred on the task with override_creds() and then passed the
NULL backing file to vfs_fadvise(). Any posix_fadvise(), readahead()
or madvise(MADV_WILLNEED) on such a file oopsed. fio triggers it at
file open with its default invalidate and fadvise_hint settings.
Fall back to generic_fadvise() when there is no backing file, as the
other passthrough helpers fall back to their extent map or generic
implementations. generic_fadvise() already ignores advice on DAX
inodes while keeping the EINVAL and ESPIPE checks.
