rbd: get rid of RBD_MAX_SEG_NAME_LEN
RBD_MAX_SEG_NAME_LEN represents the maximum length of an rbd object name (i.e., one of the objects providing storage backing an rbd image). Another symbol, MAX_OBJ_NAME_SIZE, is used in the osd client code to define the maximum length of any object name in an osd request. Right now they disagree, with RBD_MAX_SEG_NAME_LEN being too big. There's no real benefit at this point to defining the rbd object name length limit separate from any other object name, so just get rid of RBD_MAX_SEG_NAME_LEN and use MAX_OBJ_NAME_SIZE in its place.
