Analyze and fix the following issue in the Linux kernel code: IB/ipath: Fix receiving UD messages with immediate data
Problem Details: This fixes a small bug in ipath_ud_rcv()'s handling of UD messages with immediate data.

Otherwise the wrong header size will be ...

Problem Details: When adding an invalid LUN, there is a deadlock between the add via scsi_scan_target and the slave_destroy handler: The handler waits for the scan to complete, but for an invalid unit, scsi_scan_target directly calls the slave_destroy handler. Fix the deadlock by removing the wait in the slave_destroy...
