Arnd Bergmann 11648b8339 sparc64: fix adjtimex regression 
Anatoly Pugachev reported one of the y2038 patches to introduce
a fatal bug from a stupid typo:

[   96.384129] watchdog: BUG: soft lockup - CPU#8 stuck for 22s!
...
[   96.385624]  [0000000000652ca4] handle_mm_fault+0x84/0x320
[   96.385668]  [0000000000b6f2bc] do_sparc64_fault+0x43c/0x820
[   96.385720]  [0000000000407754] sparc64_realfault_common+0x10/0x20
[   96.385769]  [000000000042fa28] __do_sys_sparc_clock_adjtime+0x28/0x80
[   96.385819]  [00000000004307f0] sys_sparc_clock_adjtime+0x10/0x20
[   96.385866]  [0000000000406294] linux_sparc_syscall+0x34/0x44

Fix the code to dereference the correct pointer again.
