[PATCH 5.10 17/21] erofs: remove the occupied parameter from z_erofs_pagevec_enqueue()

[Greg Kroah-Hartman]

From: Yue Hu <huyue2@xxxxxxxxxx>

commit 7dea3de7d384f4c8156e8bd93112ba6db1eb276c upstream.

No any behavior to variable occupied in z_erofs_attach_page() which
is only caller to z_erofs_pagevec_enqueue().
