Add bounds checking asserts to memmap IO driver

The memmap IO driver doesn't perform bounds check when reading, writing,
or seeking. The onus to vet parameters is on the caller, and this patch
asserts that:

  - non-negative size is specified for for backing memory;

  - valid parameters are passed into the driver for read, write and seek
    operations.
