path: remove redundant function calls

repo_settings_get_shared_repository() is invoked multiple times in
calc_shared_perm(). While the function internally caches the value,
repeated calls still add unnecessary noise.

Store the result in a local variable and reuse it instead. This makes
it explicit that the value is expected to remain constant and avoids
repeated calls in the same scope.
