tools/rbd/Utils.cc: yank features_set_specified and related logic

since it isn't used

Fix for:

CID 1394854 (#1 of 1): 'Constant' variable guards dead code (DEADCODE)
 dead_error_line: Execution cannot reach this statement:
 opts->set(RBD_IMAGE_OPTION_....
 Local variable features_set_specified is assigned only once, to a
 constant value, making it effectively constant throughout its scope.
