LU-16123 checkpatch: Suppress false warning

checkpatch throws a warning if it finds an "UPPERCASE"
on the left and side. According to the script/code it
is to avoid cases like "foo + BAR < baz".

Warnings example:
(style)  Comparisons should place the constant on \
the right side of the test

However for our case which throws a warning as false
positive.

"#if LUSTRE_VERSION_CODE < OBD_OCD_VERSION(3, 0, 53, 0)
...
"#endif

This patch suppresses the warning thrown by above
code only. This is not a generic "left hand" upper-case
warning suppressor which can be a genuine error. This
only handles the case where the left side is
LUSTRE_VERSION_CODE upper-case macro.
