drm/udl: Move drm_dev_{enter, exit}() into udl_get_edid_block()

Browse source

Protect the code in udl_get_edid_block() with drm_dev_enter() and
drm_dev_exit(), so that all callers automatically invoke it. The
function uses hardware resources, which can be hot-unplugged at
any time. The other code in udl_connector_detect() does not use the
resources of the hardware device and therefore does not require
protection.

This change will allow to use udl_get_edid_block() in various
contexts easily.
