Subject: [PATCH] ufs: Remove redundant inode number check from ufs_nfs_get_inode

From: Sergii Boryshchenko <sergii.boryshchenko@...ballogic.com>

The `ufs_nfs_get_inode` function contains a check to validate the inode number
(`ino`) against the valid range of inode numbers. However, this check is
redundant because the same validation is already performed in the `ufs_iget`
function, which is called immediately afterward.

By removing this redundant check, we simplify the code and avoid unnecessary
double-checking of the inode number, while still ensuring that invalid inode
numbers are properly handled by the `ufs_iget` function.

This change has no impact on the functionality since `ufs_iget` provides the
necessary validation for all callers.
