This patch is to make sure that during a pci error, the remove_one
function frees the resources even though the hardware command failed
to avoid memory leaks when the adapter recovers.  Also make sure that
remove_one function goes thru all the functions like disable all irqs
and disable pci so when the remove_one function is done then the eehd
daemon will continue the recovery process.
