lib: Clarify the return value of strnlen_user()
strnlen_user() can return a number in a range 0 to count +
sizeof(unsigned long) - 1. Clarify the comment at the top of the
function so that users don't think the function returns at most count+1.

[ Also added commentary about preferably not using this function ]
