freebsd32: aio_cancel takes a struct aiocb32

Strictly speaking, it takes a virtual address and doesn't touch the
object directly, but this is consistant with other aio_*() syscalls.

fspacectl: remove unneeded freebsd32 wrapper

fspacectl(2) does not require special handling on freebsd32. The
presence of off_t in a struct does not cause it's size to change
between the native ABI and the 32-bit ABI supported by freebsd32
because off_t is always int64_t on BSD systems. Further, byte
order only requires handling for paired argument or return registers.

(32-byte alignment of 64-bit objects on i386 can require special
handling, but that situtation does not apply here.)

freebsd32: rename 32-bit compat pads to _pad

Some 32-bit architectures pass 64-bit values in aligned

Some 32-bit architectures pass 64-bit values in aligned

explicitly from compat code. We also sometimes add pads in the default
ABI. Differentiate the two by making the freebsd32 ones int _pad.
In a future commit the 32-bit ones will be automatically generated.
