scsi: 3ware: fix return 0 on the error path of probe

[ Upstream commit 4dc98c1995482262e70e83ef029135247fafe0f2 ]

tw_probe() returns 0 in case of fail of tw_initialize_device_extension(),
pci_resource_start() or tw_reset_sequence() and releases resources.
twl_probe() returns 0 in case of fail of twl_initialize_device_extension(),
pci_iomap() and twl_reset_sequence().  twa_probe() returns 0 in case of
fail of tw_initialize_device_extension(), ioremap() and
twa_reset_sequence().

The patch adds retval initialization for these cases.
