sna: Suppress log messages for unchanging EDID
Whenever we reprobe an unchanging output and re-read its EDID, we emit a
useless log message. Previously this was squelched by trying to spot
when an EDID was unchanged through the use of its blob.id, however we
need to do a complete check on the contents in case the kernel returns
us a new EDID with the old id. So make a temporary copy of the current
EDID data and only squelch the log messages if the new EDID is an exact
match.
