[PATCH] drm/msm/hdmi: remove unnecessary NULL check

This code was refactored in commit 69a88d8633ec ("drm/msm/hdmi: move
resource allocation to probe function") and now the "hdmi" pointer can't
be NULL.  Checking causes a Smatch warning:

    drivers/gpu/drm/msm/hdmi/hdmi.c:141 msm_hdmi_init()
    warn: variable dereferenced before check 'hdmi' (see line 119)
