scsi: qla2xxx: Use flag PFLG_DISCONNECTED.

Browse Source 
There is already flag defined PFLG_DISCONNECTED, which is set
for PCI or register disconnect error condition. There is no need to have
flag PCI_ERR, which has same purpose. Remove use of PCI_ERR flag and use
PFLG_DISCONNECTED flag during error condition.
