Convert the existing user of cpu{mask|list}_scnprintf() and
node{mask|list}_scnprintf() which use them just to printk or
seq_printf() the resulting buffer to use the following functions
instead respectively.
* For printk: cpu{mask|list}_pr_cont() and node{mask|list}_pr_cont().
* For seq_file: seq_cpumask[_list]() and seq_nodemask[_list]().
Because these conversions usually break up a single output function
call into multiple, the reduction is LOC isn't too big but it removes
unnecessary complexity and/or arbitrary limit on the length printed.
This patch is dependent on the previous patch ("bitmap, cpumask,
nodemask: implement pr_cont variants of formatting functions") which
is planned to go through -mm. It'd be the easiest to route this
together. If this should go through the subsystem tree, please wait
till the forementioned patch is merged to mainline.
