[PATCH 03/10] mountd: Eliminate unnecessary type conversions

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

Clean up compiler warnings:

cache.c:332:16: warning: conversion to ‘int’ from ‘size_t’ may alter
  its value [-Wconversion]
cache.c:339:9: warning: conversion to ‘size_t’ from ‘int’ may change
  the sign of the result [-Wsign-conversion]
cache.c: In function ‘subexport’:
cache.c:354:17: warning: conversion to ‘int’ from ‘size_t’ may alter
  its value [-Wconversion]
cache.c:357:9: warning: conversion to ‘size_t’ from ‘int’ may change
  the sign of the result [-Wsign-conversion]

Seen with gcc version 4.6.3 20120306 (Red Hat 4.6.3-2) (GCC) .
