sparc64: Fix prototype warnings in traps_64.c

Fix the following warnings:
arch/sparc/kernel/traps_64.c:253:6: warning: no previous prototype for ‘is_no_fault_exception’
arch/sparc/kernel/traps_64.c:2035:6: warning: no previous prototype for ‘do_mcd_err’
rch/sparc/kernel/traps_64.c:2153:6: warning: no previous prototype for ‘sun4v_nonresum_error_user_handled’

In all cases make the function static as there were no users outside
traps_64.c
