smbd: Simplify dropbox special case in unix_convert
EACCESS needs special treatment: If we want to create a fresh file,
return OBJECT_PATH_NOT_FOUND, so that the client will continue creating
the file. If the client wants us to open a potentially existing file,
we need to correctly return ACCESS_DENIED.
This patch makes this behaviour hopefully a bit clearer than the code
before did.
