ntfs: propagate the ntfs_attr_iget() error in update_reparse_data()

Browse Source 
update_reparse_data() replaces the ntfs_attr_iget() error with -EINVAL,
so an -ENOMEM from iget5_locked() or a read failure from
ntfs_read_locked_attr_inode() is reported to userspace as EINVAL.

The path is reached from __ntfs_create() via the three
ntfs_reparse_set_*() helpers, so symlink() and mknod() are affected.

Return PTR_ERR(rp_inode) instead.
