[PATCH 06/10] mountd: Avoid unnecessary type conversions

[Chuck Lever <chuck.lever@oracle.com>]

Clean up compiler warnings:

cache.c: In function ‘is_subdirectory’:
cache.c:760:16: warning: conversion to ‘int’ from ‘size_t’ may
  alter its value [-Wconversion]
cache.c:763:3: warning: conversion to ‘size_t’ from ‘int’ may
  change the sign of the result [-Wsign-conversion]
