Subject: [PATCH v3 1/2] asm-generic/bug.h: declare struct pt_regs; before function prototype

The declaration of `__warn()` has `struct pt_regs *regs` as one of its
parameters.  This can result in compiler warnings if `struct regs` is
not already declared.  Add an empty declaration of `struct pt_regs` to
avoid the warnings.

v3: Actually, there was no v1 or v2.  I called this v3 to match the
series.
