storage/posix: do not dereference gfid symlinks before posix_handle_mkdir_hashes()
Whenever a new directory is created, its corresponding gfid file must also be created. This was done first calling MAKE_HANDLE_PATH() to get the path of the gfid file, then calling posix_handle_mkdir_hashes() to create the parent directories of the gfid, and finally creating the soft-link. In normal circumstances, the gfid we want to create won't exist and MAKE_HANDLE_PATH() will return a simple path to the new gfid. However if the volume is damaged and a self-heal is running, it is possible that we try to create an already existing gfid. In this case, MAKE_HANDLE_PATH() will return a path to the directory instead of the path to the gfid. To solve this problem, every time a path to a gfid is needed, a call to MAKE_HANDLE_ABSPATH() is made instead of the call to MAKE_HANDLE_PATH().
