PATCH, libjava: silence unsued parameter warning

[Ben Elliston]

This patch silences a warning about 'object' being unused in
_Jv_JNI_GetObjectRefType.  Committed as obvious, given that MAYBE_UNUSED
is used elsewhere in the libjava tree.  Tested with a bootstrap and make
check-target-libjava.

	* jni.cc (_Jv_JNI_GetObjectRefType): Mark `object' parameter as
	maybe unused.
