fs/ntfs3: Fix memory leak if fill_super failed

mainline inclusion
from mainline-v5.15
commit 9b75450d
category: feature
bugzilla:
https://gitee.com/openeuler/kernel/issues/I4G67J?from=project-issue


CVE: NA

----------------------------------------------------------------------

In ntfs_init_fs_context we allocate memory in fc->s_fs_info.
In case of failed mount we must free it in ntfs_fill_super.
We can't do it in ntfs_fs_free, because ntfs_fs_free called
with fc->s_fs_info == NULL.
fc->s_fs_info became NULL in sget_fc.
