Tetsuo Handa 8414983c2e fs/ntfs3: don't hold ni_lock when calling truncate_setsize() 
[ Upstream commit 0226635c30 ]

syzbot is reporting hung task at do_user_addr_fault() [1], for there is
a silent deadlock between PG_locked bit and ni_lock lock.

Since filemap_update_page() calls filemap_read_folio() after calling
folio_trylock() which will set PG_locked bit, ntfs_truncate() must not
call truncate_setsize() which will wait for PG_locked bit to be cleared
when holding ni_lock lock.
