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.

Changes since v1:
- Removed the unused variable 'uspi' as reported by the kernel test robot.
