qcacmn: Add check for mem debug disabled in qdf_frag_debug_update_addr

Check for is_initial_mem_debug_disabled is missing in API
qdf_frag_debug_update_addr API. Add check for is_initial_mem_debug_disabled
so as to return without proceeding further when
is_initial_mem_debug_disabled is set to true.
