drm/i915: Clear crtc atomic flags at beginning of transaction
Once we have full atomic modeset, these kind of flags should be in a
real intel_crtc_state that's tracked properly. In the meantime, make
sure we clear out any old flags at the beginning of a transaction so
that we don't wind up seeing leftover flags from old transactions that
were checked, but never went to the commit step. At the moment, a
failed check or prepare could leave stale flags behind that interfere
with the next atomic transaction.
v2: Just do a memset; the series this patch was originally part of
placed additional fields into the structure that shouldn't be
cleared, but that's no longer the case.
