Kernel/Storage: Recover from fatal AHCI error on TFES, HBDS and HBFS

Browse source 
These errors are classed as fatal, so we need to recover from them.
Found while trying to debug AHCI boot on VMware Player,
where I got TFES.

From the spec: "Fatal errors (signified by the setting of PxIS.HBFS,
PxIS.HBDS, PxIS.IFS, or PxIS.TFES) will cause the HBA to enter
the ERR:Fatal state"

We were already recovering from IFS.
