Before introducing redirect_dir feature, the condition
!ovl_lower_positive(dentry) for a directory, implied that it is a pure
upper directory, which may be removed if empty.
Now that directory can be redirect, it is possible that upper does not
cover any lower (i.e. !ovl_lower_positive(dentry)), but the directory is a
merge (with redirected path) and maybe non empty.
Check for this case in ovl_remove_upper().
This change fixes the following test case from rename-pop-dir.py
of unionmount-testsuite:
"""Remove dir and rename old name"""
d = ctx.non_empty_dir()
d2 = ctx.no_dir()
ctx.rmdir(d, err=ENOTEMPTY)
ctx.rename(d, d2)
ctx.rmdir(d, err=ENOENT)
ctx.rmdir(d2, err=ENOTEMPTY)
./run --ov rename-pop-dir
/mnt/a/no_dir103: Expected error (Directory not empty) was not produced
