Script fails when ran on a system with H310 chipset motherboard

flash-it/README.md

Line 91 in e50b122

* Server or other computer with only the target adapter installed and visible to the OS

This point does not take into account that there could be other PCI devices, not necessarily SAS HBAs, that could get matched by the script.

I ran into this issue when I tried crossflashing on a system with an H310 chipset motherboard. A workaround for this is either modifying the 'ADAPTER_PATTERN' variable or setting the PCI address in the file referenced by the variable 'BACKUP_PCI_ADDRESS_FILE'. I don't think the script itself needs changing, an update to the README.md should be sufficient

The pattern could be updated with a negative look-ahead to explicitly exclude those boards which are known to be mistakenly identified.
