drm/i915: cleanup use of INSTR_CLIENT_MASK
commit e3f51ece02f877d2ce9619aa8d5919db56f39582 upstream.
Doing cmd_header >> 29 to extract our 3-bit client value where we know
cmd_header is a u32 shouldn't then also require the use of a mask. So
remove the redundant operation and get rid of INSTR_CLIENT_MASK now that
there are no longer any users.
