    Linux: Do not initialize msghdr's msg_iter/msg_iov
    
    Since the initial Linux commit (2.6.12-rc2) the Linux function
    kernel_recvmsg() handles the initialization of the msghdr members
    related to the iov (msghdr.msg_iter and for earlier kernels
    msghdr.msg_iov and msghdr.msg_iovlen).
    
    The code in osi_NetReceive for Linux unnecessarily initializes these
    structure members prior to calling kernel_recvmsg().
    
    Remove the unnecessary code from osi_NetReceive along with the
    surrounding preprocessor check for STRUCT_MSGHDR_HAS_MSG_ITER.  Since
    this is the only location that uses this define, also remove the
    associated autoconf test.
    
    NOTE: This was discovered while investigating changes needed for
    Linux 6.4, due to: "iov_iter: add iter_iovec() helper" (de4f5fed3f)
    which renamed the Linux structure iter_iovec's member iov to __iov.
    Since the openafs code that was affected by the Linux 6.4 change is
    being removed as unnecessary, this commit is not Linux 6.4 specific,
    but effects all versions of Linux.
