This is a leftover from commit 
ce1fc9345a59 ("kconfig: do not clear
SYMBOL_DEF_USER when the value is out of range").
This code is now redundant because if a user-supplied value is out
of range, the value adjusted by sym_validate_range() differs, and
conf_unsaved has already been incremented a few lines above.
