rgw: change RGWOp::name() to return string instead of char*

Return 'const string' instead of 'const char *' from RGWOp::name() to
avoid the usage of std::string:c_str() to return 'const char *' in
some cases in rgw_rest_replica_log.h.

Returning result of c_str() from a function is dangerous since the
result gets (may) invalid after the related string object gets
destroyed or out of scope (which is the case with return). So you
may end up with garbage in this case.

Related warning from cppcheck:
 [src/rgw/rgw_rest_replica_log.h:39]: (error) Dangerous usage of
  c_str(). The value returned by c_str() is invalid after this call.
 [src/rgw/rgw_rest_replica_log.h:59]: (error) Dangerous usage of
  c_str(). The value returned by c_str() is invalid after this call.
 [src/rgw/rgw_rest_replica_log.h:79]: (error) Dangerous usage of
  c_str(). The value returned by c_str() is invalid after this call

This should also fix:

CID 1049250 (#1 of 1): Wrapper object use after free (WRAPPER_ESCAPE)
  escape: The internal representation of "s" escapes, but is destroyed
  when it exits scope.
CID 1049251 (#1 of 1): Wrapper object use after free (WRAPPER_ESCAPE)
  escape: The internal representation of "s" escapes, but is destroyed
  when it exits scope.
CID 1049252 (#1 of 1): Wrapper object use after free (WRAPPER_ESCAPE)
  escape: The internal representation of "s" escapes, but is destroyed
  when it exits scope.
