i965/fs: Drop bogus writemasking disable bit from HALT instructions.

This may have been the reason people ran into problems with
non-uniform HALT instructions and ended up using the inefficient
ANY16H/ANY8H predicates instead of ANY4H or NORMAL in order to prevent
non-uniform discard.  The HALT instruction is able to handle
non-uniform execution masks just fine.
