typo fix in arch/x86/kernel/asm_offset_64.c

[Nicholas Mc Guire <der.herr@hofr.at>]

drope double entry for pt_regs_bx

This seems to be a typo - resulting in a double entry in the
generated include/generated/asm-offsets.h which is not necessary

Build-tested and booted on x86 64 box to make sure it was not
doing any strange magic.... after all it was in the kernel in
this form for almost 10 years.
