checkpatch.pl: be silent when -q and --ignore is given

Fix checkpatch.pl when both -q and --ignore are given and prevents it from
printing a

NOTE: Ignored message types: blah

messages.

E.g., if I use -q --ignore PREFER_PACKED,PREFER_ALIGNED, i see:

NOTE: Ignored message types: PREFER_ALIGNED PREFER_PACKED

It makes no sense to print this when -q is given.
