stmhal/diskio: Add provision for default returns for ioctl INIT/SEC_SIZE.
stmhal/diskio: Add provision for default returns for ioctl INIT/SEC_SIZE.

If None was returned for such requests (which likely means that user simply
didn't handle them), it means successful init and default sector size of 512
bytes respectively. This makes only BP_IOCTL_SEC_COUNT a mandatory request,
and thus re-establishes parity with old interface, where only .count() is
mandatory().
