autofs-5.1.7 - eliminate redundant cache lookup in tree_mapent_add_node()

Since we need to create the offset tree after adding the offset entries
|
|
|
4bca17 |
to the mapent cache (from a list.h list) there's no need to lookup the
|
|
|
4bca17 |
mapent in tree_mapent_add_node() and validate it. Just use it directly
|
|
|
4bca17 |
when calling tree_mapent_add_node() and avoid a cache lookup on every
|
|
|
4bca17 |
node addition.
