[PATCH] ncpfs: remove unused redundant variables

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The variables oldnamelen, oldprivatelen and oldlen are assigned but
are never read and are redundant. Remove them. Cleans up the clang
build warnings:

fs/ncpfs/ioctl.c:674:4: warning: Value stored to 'oldnamelen' is
never read
fs/ncpfs/ioctl.c:676:4: warning: Value stored to 'oldprivatelen' is
never read
fs/ncpfs/ioctl.c:770:4: warning: Value stored to 'oldlen' is never
read
