lsi: check if SIGP bit is already set in Wait reselect
If SIGP is set, the 'Wait for Reselection' command should jump immediately to the address stored in the second DWORD of the instruction. This fixes spurious hangs in the HP-UX 11.11 installer when the SIGP bit gets set by the kernel before the 'Wait for Reselection' command is executed by SCRIPTS.
