ovl: fix copy-up in tmpfile
Move ovl_copy_up() call outside of ovl_want_write()/ovl_drop_write()
region, since copy up may also call ovl_want_write() resulting in recursive
locking on sb->s_writers.

Closes: https://lore.kernel.org/all/[email protected]/
Fixes: 9a87907de359 ("ovl: implement tmpfile")
