[PATCH 05/10] mountd: Avoid unnecessary type conversions

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

Clean up compiler warnings:

cache.c: In function ‘get_uuid’:
cache.c:249:2: warning: conversion to ‘size_t’ from ‘int’ may change
  the sign of the result [-Wsign-conversion]

And the like.

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