[PATCH v1 3/5] SUNRPC: Clean up xdr_commit_encode()

[Chuck Lever <chuck.lever@xxxxxxxxxx>]

Both the ::iov_len field and the third parameter of memcpy() and
memmove() are size_t. There's no reason for the implicit conversion
from size_t to int and back. Change the type of @shift to make the
code easier to read and understand.
