Make `send_bufs_with_fd(s)` take `IoSlice` instead of `&[u8]`.
Note that no Chrome OS-side is needed for this API change because these
methods aren't used in any other Chrome OS projects.

This reverts commit b975546c3f.
Reason for revert: mlock is insufficient to prevent migration/compacting of guest memory, and therefore pKVM has been modified to perform pinning in the kernel, making the mlock call superfluous.
Original change's description:
> vm-memory: mlock2(MLOCK_ONFAULT) guest memory for protected VMs
>
> By default, the memory of a protected VM is inaccessible to the host
> and crosvm. Consequently, attempts to access guest memory are fatal and
> must be avoided in order for the guest to run.
>
> Mlock guest pages as they are faulted in for protected VMs, ensuring
> that the host doesn't try to age or swap them out as a result of memory
> pressure.

`sys_util::recv_iovecs_with_fds` was implemented as a safe function, but
it was actually unsafe because it assumed that the caller would give a
slice of `libc::iovec` where each `iov_base` points a valid memory
region with `iov_len`.
To make the function truly safe, it should take a slice of IoSliceMut
instead.
