cifs: fix handling of scopeid in cifs_convert_address

commit 9616125611ee47693186533d76e403856a36b3c8 upstream.

The code finds, the '%' sign in an ipv6 address and copies that to a
buffer allocated on the stack. It then ignores that buffer, and passes
'pct' to simple_strtoul(), which doesn't work right because we're
comparing 'endp' against a completely different string.

Fix it by passing the correct pointer. While we're at it, this is a
good candidate for conversion to strict_strtoul as well.
