[PATCH 2/8] x86: remove pointless 2nd parameter from check_VecOperations()

[Jan Beulich]

In the one case where non-NULL gets passed, passing NULL has the same
effect. Hence the parameter is not needed at all.

	* config/tc-i386.c (check_VecOperations): Remove 2nd parameter.
	(i386_att_operand): Adjust calls to check_VecOperations.
	* config/tc-i386-intel.c (i386_intel_operand): Likewise.
