[SCSI] areca: improve driver stability and compatibility
Description:
1. Implement PCI-Express error recovery function and AER
capability, especially thanks to Yanmin Zhang's openhanded help
about AER
2. Implement the selection of ARCMSR_MAX_XFER_SECTORS_B=4096 if
firmware version is latter than 1.42
3. Add arcmsr_done4_abort_postqueue in arcmsr_iop_reset function
to improve the stability as hot-unplug/plug
4. Modify the ISR, arcmsr_interrupt routine, to prevent the
inconsistency with sg_mod driver if application directly calls
the arcmsr driver w/o passing through scsi midlayer
