[misc] fix small issues

* SetAutoMount()/GetAutoMount() should check for INVALID_HANDLE_VALUE and not NULL.
  Also we don't actually need to open MOUNTMGR_DOS_DEVICE_NAME rw to issue an IOCTL.
* ToggleEsp() failed to exit properly when an ESP offset was specified.
* Introduce PI_MAX to explicitly set the size of the partition_information table.
* write_sectors() has write retry, so there's no need to perform one on top of it.
* When we exit FormatThread(), GetLogicalName() should attempt to look for the the
  main partition and be silent.
