alloc_tag: handle module codetag load errors as module load failures

Failures inside codetag_load_module() are currently ignored.  As a result
an error there would not cause a module load failure and freeing of the
associated resources.  Correct this behavior by propagating the error code
to the caller and handling possible errors.  With this change, error to
allocate percpu counters, which happens at this stage, will not be ignored
and will cause a module load failure and freeing of resources.  With this
change we also do not need to disable memory allocation profiling when
this error happens, instead we fail to load the module.
