Deepak Nibade 0057d09aa2 gpu: nvgpu: do not disable SM exceptions for BPT_INT ...

In gr_gk20a_handle_sm_exception(), we disable all SM exceptions
if SM debug mode is set and irrespective of exception type

But we should not disable SM exceptions if the only
exception is BPT_INT

Fix this by checking if only interrupt is BPT_INT and
do not disable SM exceptions in that case

Note that for rest of the exceptions we still need to
disable SM exceptions

Also, remove redudant checks of sm_debugger_attached since
we bail out early if this flag is not set anyways
