smb: client: fix WSL reparse point uid/gid override

Browse source

wsl_to_fattr() unconditionally overwrites cf_uid/cf_gid with values
from WSL extended attributes ($LXUID/$LXGID), ignoring the forceuid
and forcegid mount options.

Fix this by initializing cf_uid/cf_gid to the mount defaults and
gating the $LXUID/$LXGID EA parsing on forceuid/forcegid.
