[PATCH][next] hpfs: remove redundant variable r

[Colin Ian King <colin.i.king@gmail.com>]

The variable r is being assigned a value but it isn't being read
afterwards. The assignment is redundant and so r can be removed.

Cleans up clang scan build warning:
warning: Although the value stored to 'r' is used in the enclosing
expression, the value is never actually read from 'r'
