alpha: fix decoding of osf_statfs and osf_fstatfs syscalls

Do not attempt to print struct osf_statfs as if it was the same as
struct statfs.  Since struct osf_statfs has never been decoded properly,
it is probably too late to implement a decoder, so let's just print the
pointer.

* statfs.c [ALPHA] (SYS_FUNC(osf_statfs), SYS_FUNC(osf_fstatfs)): Move ...
* alpha.c: ... here.  Replace printstatfs with printaddr.
