Use of uninitialised data in tc-sh.c

[DJ Delorie]

I think this solves it.  At least, it looks right, passes valgrind,
and passes make check.  Note that, for each case where this code
accidentally failed before, it ends up doing the right thing anyway.
(that's not an excuse, just noting this is a low priority patch)

	* config/tc-sh.c (get_specific): Only check limits when the
	operand matches the expected argument.
