gpu: nvgpu: fix the unit test traceability

gk20a_tsg_unbind_channel_check_hw_next was not added to Targets
in unit test specification. Add it.  __attribute__ in debug.h
is captured by Doxygen as function with no tests. However it
is not really a function and applies to non-fusa function so
skip it in Doxygen.
