module: Fix display of wrong module .text address
Reading file /proc/modules shows the correct address:
[root@s35lp76 ~]# cat /proc/modules | egrep '^qeth_l2'
qeth_l2 94208 1 - Live 0x000003ff80401000
and reading file /sys/module/qeth_l2/sections/.text
[root@s35lp76 ~]# cat /sys/module/qeth_l2/sections/.text
0x0000000018ea8363
displays a random address.
This breaks the perf tool which uses this address on s390
to calculate start of .text section in memory.
Fix this by printing the correct (unhashed) address.
Thanks to Jessica Yu for helping on this.
