don't correlate __verbose statics

Browse Source 
The __verbose section stores several static local structs named
"descriptor".  These structs contain information related to dynamic
debugging printks and are specific to the patched object, so they
shouldn't be correlated with their base object counterparts.

Fixes the following error:

    kpatch_correlate_static_local_variables: 830: static local variable descriptor.49967 not used
