bnx2: EEH is failing with timeout

bnx2 is failing when a PCI error is detected. The error is the
following:

bnx2: Chip not in correct endian mode
bnx2: fw sync timeout, reset code = 404001d

This error was caused because the way pci_restore_state() is working
after commit 4b77b0a2

 ("PCI: Clear
saved_state after the state has been restored").
