sparc32: make show_stack() acquire %fp if @_ksp is not specified
show_stack(current or NULL, NULL) is used by arch-independent code to dump
backtrace of the current task; however, sparc32 show_stack() doesn't
implement it and wouldn't print any backtrace when NULL @_ksp is specfied.
Make show_stack() acquire and use %fp if @tsk is NULL or current and @_ksp
is NULL. This makes %fp fetching in dump_stack() unnecessary. Make it
use NULL for @_ksp instead.
Only compile tested.
