vfs: wrap write f_ops with file_{start,end}_write()
Before calling write f_ops, call file_start_write() instead
of sb_start_write().
Replace {sb,file}_start_write() for {copy,clone}_file_range() and
for fallocate().
Beyond correct semantics, this avoids freeze protection to sb when
operating on special inodes, such as fallocate() on a blockdev.
