lib: fix memparse() to handle overflow
Since '_parse_integer_limit()' (and so 'simple_strtoull()') is now capable
to handle overflow, adjust 'memparse()' to handle overflow (denoted by
ULLONG_MAX) returned from 'simple_strtoull()'. Also use
'check_shl_overflow()' to catch an overflow possibly caused by processing
size suffix and denote it with ULLONG_MAX as well.
