Suren Baghdasaryan 9e8a0bbb12 alloc_tag: prevent enabling memory profiling if it was shut down 
Memory profiling can be shut down due to reasons like a failure during
initialization.  When this happens, the user should not be able to
re-enable it.  Current sysctrl interface does not handle this properly and
will allow re-enabling memory profiling.  Fix this by checking for this
condition during sysctrl write operation.
