NFS: use size_t type for holding rsize bytes in NFS O_DIRECT read path
size_t is used for holding byte counts, so use it for variables storing rsize.
Note that the write path will be updated as we add support for async
O_DIRECT writes.
Test plan:
Need to verify that existing comparisons against new size_t variables behave
correctly.
