PATCH 1/1 Remove unused __syscall_count

Noone complained: Linus, please apply.

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.
