[PATCH 1/5] fbdevhw: iterate over all modes that match a mode. (v2)

From: Adam Jackson <ajax at redhat.com>
So on RHEL5 anaconda sets an xorg.conf with a fixed 800x600 mode in it,
we run radeonfb and fbdev since ati won't work in userspace due to domain
issues in the older codebase.
On certain pseries blades the built-in KVM can't accept an 800x600-43 mode,
it requires the 800x600-60 mode, so we have to have the kernel radeonfb
driver reject the 800x600-43 mode when it sees it. However then fbdev
doesn't try any of the other 800x600 modes in the modelist, and we end up
getting a default 640x480 mode we don't want.
This patch changes the mode validation loop to continue on with the other modes
that match to find one that works.
v2: move code around to avoid extra loop, after comment from Jamey.
