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.

AFS is a distributed file system that enables users to share and access all of the files stored in a network of computers as easily as they access the files stored on their local machines. The file system is called distributed for this exact reason: files can reside on many different machines, but are available to users on every machine.
