gsdx-ogl: remove unsafe fbmask of the free SW blending 

Initially it was free to do the SW blending because safe fbmask
will already do a sw blending.

Unsafe version uses a fast path with a limited blending. Therefore
SW blending isn't free anymore.

Improve the speed of the previous speed hack (xenosaga 1)
