drm/vc4: hdmi: Fix pointer dereference before check

Browse source

Commit 6bed2ea3cb ("drm/vc4: hdmi: Reset link on hotplug") introduced
the vc4_hdmi_reset_link() function. This function dereferences the
"connector" pointer before checking whether it is NULL or not.

Rework variable assignment to avoid this issue.
