incorrect printk in sym_attach error path

I get this with 2.6.13, due to some ppc64 specific errors:

PCI: Enabling device: (0002:30:0c.0), cmd 143
sym0: <896> rev 0x7 at pci 0002:30:0c.0 irq 65 __sym_calloc2: failed to allocate HCB[2200] <NULL>: giving up ...
RTAS: event: 71, Type: Internal Device Failure, Severity: 2
PCI: Enabling device: (0002:30:0c.1), cmd 143
sym0: <896> rev 0x7 at pci 0002:30:0c.1 irq 66 __sym_calloc2: failed to allocate HCB[2200] <NULL>: giving up ...

attach_failed is used for more than one error.
np->s.inst_name should be assigned earlier.
