[patch v2] cifs: fix revalidation test in cifs_llseek()

[Dan Carpenter]

This test is always true so it means we revalidate the length every
time, which generates more network traffic.  When it is SEEK_SET or
SEEK_CUR, then we don't need to revalidate.

v2:  I had the test reversed in the first version.
