Ard Biesheuvel 9d63619224 ARM: 9125/1: fix incorrect use of get_kernel_nofault()
Commit 344179fc7e ("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.
