sched/walt: use do_div instead of division operator
Use do_div() instead of "/" operator to fix undefined references to
"__aeabi_uldivmod" build error for ARCH=arm.
Also in TP_fast_assign(), along with do_div() usage, replace "," with
";" which would have resulted in a syntax error (!), because
'#define TP_fast_assign(args...) args' would have stripped off the ","
and left white space between these two assignments after CPP phase.
