[WINED3D] Use correct register mask

[Ivan Gyurdiev]

According to msdn, the correct register mask is 0x07FF, which is the one 
defined in d3d9.h as well. The mask 0x1FFF which is used includes the 
high 2 bits of the register type, which will cause havoc if registers 
used those bits (Reg.Type > 7). I think this may happen in  shaders 2+.
 
Please apply after the pshader code structure/centralize patch.
