Overprotective PROTECT for path access to maps

[rebolbot]

Submitted by: abolka

Get access to a PROTECTed map! via path! results in a protection error. (Whereas SELECT works fine.)

>> m: map [a: 42]
>> protect m
>> m/a
** Script error: protected value or series - cannot modify
;; expected: == 42
