fs/ntfs3: Fix slab-out-of-bounds read in ntfs_trim_fs
Syzbot reports an out of bound access in ntfs_trim_fs.
The cause of this is using a loop termination condition that compares
window index (iw) with wnd->nbits instead of wnd->nwnd, due to which the
index used for wnd->free_bits exceeds the size of the array allocated.
Fix the loop condition.
