Simplify initcall_debug output

print_fn_descriptor_symbol() prints the address if we don't have a symbol, so
no need to print both.

Also, combine printing return value with elapsed time. Changes this:

Calling initcall 0xc05b7a70: pci_mmcfg_late_insert_resources+0x0/0x50()
initcall 0xc05b7a70: pci_mmcfg_late_insert_resources+0x0/0x50() returned 1.
initcall 0xc05b7a70 ran for 0 msecs: pci_mmcfg_late_insert_resources+0x0/0x50()
initcall at 0xc05b7a70: pci_mmcfg_late_insert_resources+0x0/0x50(): returned with error code 1

to this:

calling pci_mmcfg_late_insert_resources+0x0/0x50()
initcall pci_mmcfg_late_insert_resources+0x0/0x50() returned 1 after 0 msecs
initcall pci_mmcfg_late_insert_resources+0x0/0x50() returned with error code 1
