ntfs3: fix double free of sbi->options->nls and clarify ownership of fc->fs_private
commit 02f312754c87 ("ntfs3: fix use-after-free of sbi->options in cmp_fnames") introduced a use-after-free bug
due to improper handling of sbi->options in error paths. This resulted in crashes when superblock cleanup
is performed in ntfs_put_super.
This patch ensures that the options structure and its subfields are properly freed, preventing the memory
corruption and use-after-free errors.
Fixes: 02f312754c87 ("ntfs3: fix use-after-free of sbi->options in cmp_fnames")
