Hangbin Liu 30472935f7 netdevsim: print human readable IP address 
commit c71bc6da61 upstream.

Currently, IPSec addresses are printed in hexadecimal format, which is
not user-friendly. e.g.

  # cat /sys/kernel/debug/netdevsim/netdevsim0/ports/0/ipsec
  SA count=2 tx=20
  sa[0] rx ipaddr=0x00000000 00000000 00000000 0100a8c0
  sa[0]    spi=0x00000101 proto=0x32 salt=0x0adecc3a crypt=1
  sa[0]    key=0x3167608a ca4f1397 43565909 941fa627
  sa[1] tx ipaddr=0x00000000 00000000 00000000 00000000
  sa[1]    spi=0x00000100 proto=0x32 salt=0x0adecc3a crypt=1
  sa[1]    key=0x3167608a ca4f1397 43565909 941fa627

This patch updates the code to print the IPSec address in a human-readable
format for easier debug. e.g.

 # cat /sys/kernel/debug/netdevsim/netdevsim0/ports/0/ipsec
 SA count=4 tx=40
 sa[0] tx ipaddr=0.0.0.0
 sa[0]    spi=0x00000100 proto=0x32 salt=0x0adecc3a crypt=1
 sa[0]    key=0x3167608a ca4f1397 43565909 941fa627
 sa[1] rx ipaddr=192.168.0.1
 sa[1]    spi=0x00000101 proto=0x32 salt=0x0adecc3a crypt=1
 sa[1]    key=0x3167608a ca4f1397 43565909 941fa627
 sa[2] tx ipaddr=::
 sa[2]    spi=0x00000100 proto=0x32 salt=0x0adecc3a crypt=1
 sa[2]    key=0x3167608a ca4f1397 43565909 941fa627
 sa[3] rx ipaddr=2000::1
 sa[3]    spi=0x00000101 proto=0x32 salt=0x0adecc3a crypt=1
 sa[3]    key=0x3167608a ca4f1397 43565909 941fa627
