mm/slub.c: parse slub_debug O option in switch statement
By moving the O option detection into the switch statement, we allow this
parameter to be combined with other options correctly. Previously options
like slub_debug=OFZ would only detect the 'o' and use DEBUG_DEFAULT_FLAGS
to fill in the rest of the flags.
