Florian Tobias Schandinat 521594442c viafb: fix rmmod bug 
This fixes a bug caused by changing pointers (viafb_mode, viafb_mode1)
assigned by module_param.  It reduces driver complexity by not needlessly
changing these vars as they are only read once and removing now
superfluous code.

On unpatched kernels loading viafb with viafb_mode or viafb_mode1 option
used and afterwards unloading it results in:

This is caused by the current code changing the pointers assigned by
module_param.  During unload it tries to free the memory the pointers
point at which is now part of an internal structure.

The patch simply avoids changing the pointers.  This is okay as they are
read only once during the initialization process.
