[PATCH] lib/vasnprintf.c: Add information to make integer comparison logical

[Bjarni Ingi Gislason]

  A question (comment) from the compiler (gcc 8.2):

../lib/vasnprintf.c:5107:35: warning: comparison of integer expressions of 
different signedness: 'int' and 'size_t' {aka 'long unsigned int'} 
[-Wsign-compare]
                         if (count < maxlen
                                   ^
  The value of "count" is tested to be non-negative, so a cast to
"size_t" is valid.
