Allow linear swizzle mode with tiled image requests.

Browse Source 
Mesa address lib faults if the only acceptable swizzle modes are
forbidden.  The old address lib simply ignored the forbidden list
in this case.  Mesa addrlib will not select linear unless there
is no other option so allowing linear mode for tiled images will
still use tiled modes when possible.
