usertools: check 0-division with hugepage size
The default page size can be None, and the page size from user request can be 0 kB if lower than 1024. In these cases, a division will fail. In order to avoid a Python exception, the page size is checked and an error message "Invalid page size" is printed. A similar error message is printed in set_hugepages() if the size is not supported, except at this stage the message can be completed with "Valid page sizes". Unfortunately the first check is too early to print such information. A third error message can be printed in a different place (get_memsize) in case of a format issue, e.g. a negative size. The function get_memsize() is also used for total requested size, so the error message "not a valid page size" was potentially wrong. This message is replaced with the more general "is not a valid size".
