PatR c0441126b8 fix #K3912 - engraving sanity: closed doors ...

Engraving in an empty doorway and then using locking magic to create
a door there resulted in an impossible warning: "engraving sanity:
illegal surface (23)" if the 'sanity_check' option was On (wizard
mode only).  Engraving in an open doorway and then simply closing
the existing door produced the same effect.

Accept engravings at closed doors.  Presumably hero will be using
Passes_walls to attempt that so treat closed doors same as open ones.
Update the engraving sanity check to deal with that.

Bonus fix: engraving sanity checking stopped after the first problem
instead of checking every engraving.  Have it continue instead.

Not fixed:  vault wall repair and temporary corridor removal does
not delete engravings and can trigger the illegal surface warning if
player engraves before the repairs.  I didn't test shop wall repair
but it doesn't have any engr references so probably has the same bug.
