s390/ipl: Fix FCP WWPN and LUN format strings for read
The following git commit changed the behavior of sscanf:

sscanf: don't ignore field widths for numeric conversions
This broke the WWPN and LUN sysfs attributes for s390 reipl and dump
on panic.
Example:
$ echo 0x0123456701234567 > /sys/firmware/reipl/fcp/wwpn
$ cat /sys/firmware/reipl/fcp/wwpn
0x0001234567012345
So fix this and use format strings that work also with the
new sscanf implementation:
$ echo 0x012345670123456789 > /sys/firmware/reipl/fcp/wwpn
$ cat /sys/firmware/reipl/fcp/wwpn
0x0123456701234567
