[BNX2]: Fix bug in irq handler and add prefetch
Fix bug in bnx2_interrupt() that caused an unnecessary register read. The BNX2_PCICFG_MISC_STATUS should only be read when the status tag has not changed. Add prefetch of the status block in bnx2_msi() similar to tg3_msi(). The status block is not touched in bnx2_msi() and prefetching it will speed up bnx2_poll() that will run on the same CPU that received the MSI. Update version.
