ntfs: fix uninitialized variable in ntfs_map_runlist_nolock
Smatch reported that ctx_needs_reset could be used uninitialized if
ntfs_map_runlist_nolock() fails early when a search context is provided.
Specifically, if the function returns -EIO because the attribute is
resident, the code jumps to err_out. This initializes ctx_needs_reset to
false to satisfy the static checker.
