Konstantin Komarov 39aef9080f fs/ntfs3: avoid calling run_get_entry() when run == NULL in ntfs_read_run_nb_ra()

[ Upstream commit c5226b96c0 ]

When ntfs_read_run_nb_ra() is invoked with run == NULL the code later
assumes run is valid and may call run_get_entry(NULL, ...), and also
uses clen/idx without initializing them. Smatch reported uninitialized
variable warnings and this can lead to undefined behaviour. This patch
fixes it.
