Simplify initcall_debug output

Browse source 
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
