[PATCH v13 09/36] test-dyndbg: fixup CLASSMAP usage error

[Jim Cromie <jim.cromie@gmail.com>]

commit 6ea3bf466ac6 ("dyndbg: test DECLARE_DYNDBG_CLASSMAP, sysfs nodes")

A closer look at test_dynamic_debug.ko logging output reveals a macro
usage error:

lib/test_dynamic_debug.c:105 [test_dynamic_debug]do_cats =p "LOW msg\n" class:MID
lib/test_dynamic_debug.c:106 [test_dynamic_debug]do_cats =p "MID msg\n" class:HI
lib/test_dynamic_debug.c:107 [test_dynamic_debug]do_cats =_ "HI msg\n" class unknown, _id:13

107 says: HI is unknown, and 105,106 have a LOW/MID and MID/HI skew.

DECLARE_DYNDBG_CLASSMAP() _base arg must equal the enum's 1st value,
in this case it was _base + 1.  This leaves HI class un-selectable.

NB: the macro could better validate its arguments.
