[SPARC64]: Fix most sparse warnings in arch/sparc64/kernel/sys_sparc.c

Browse source 
Sparse still doesn't like the funny cast we make from a scalar to a
"union semun" (which is correct by the C language and in particular
works with the sparc64 calling conventions, but sparse doesn't grok
that yet).
