LU-6215 lprocfs: handle seq_printf api change

LU-6215 lprocfs: handle seq_printf api change

Starting with the 4.3 linux kernel seq_printf is a void
function not returning the character count. This work
updates lustre to treat seq_printf as a void function.
Fixed alignment issues and ran this patch against the
Linux kernels checkpatch to make it compliant to
upstream standards.
