x86: Remove unnecessary vex.w check for xh_mode in disassembler

Browse source 
For all the xh_mode usage in table, they are all using %XH, which will
print "{bad}" while EVEX.W=1. This makes this vex.w check unnecessary.

opcodes/ChangeLog:

	* i386-dis.c (OP_E_memory): Remove vex.w check for xh_mode.
