ARM: 9125/1: fix incorrect use of get_kernel_nofault()
Commit 344179fc7ef4 ("ARM: 9106/1: traps: use get_kernel_nofault instead of set_fs()") replaced an occurrence of __get_user() with get_kernel_nofault(), but inverted the sense of the conditional in the process, resulting in no values to be printed at all. I.e., every exception stack now looks like this: Exception stack(0xc18d1fb0 to 0xc18d1ff8) 1fa0: ???????? ???????? ???????? ???????? 1fc0: ???????? ???????? ???????? ???????? ???????? ???????? ???????? ???????? 1fe0: ???????? ???????? ???????? ???????? ???????? ???????? which is rather unhelpful.
