Subject: [PATCH] hpfs: remove redundant variable r

Variable r is being assigned a value that is never used, the assignment
and the variable are redundant and can be removed.

Cleans up clang scan warning:
fs/hpfs/namei.c:560:8: warning: Although the value stored to 'r' is
used in the enclosing expression, the value is never actually read
from 'r' [deadcode.DeadStores]
