Linus, please apply, unless someone has plans for this field.

Noone seems to use __syscall_count. Remove the field from i386
irq_cpustat_t struct, and the generic accessor macros.

Because some archs have hardcoded asm references to offsets in this
structure, I haven't touched non-x86, but doing so is usually
trivial.
