Subject: libceph: change ceph_pagelist_encode_string() to take u32
Git-commit: c9ed51c9123ab5e8f79b7d53a9afd786b43d4fe6
Patch-mainline: v4.19-rc1
References: FATE#324714

The wire format dictates that the length of string fits into 4 bytes.
Take u32 instead of size_t to reflect that.

We were already truncating len in ceph_pagelist_encode_32() -- this
just pushes that truncation one level up.
