process.

TEE_ERROR_NO_DATA and TEE_ERROR_ITEM_NOT_FOUND. We initialize
the item when return these value.

Jason Zhu 615e0cde57 lib: avb: fix bug HANG in fastboot getvar at-vboot-state 
Bug: Run 'fastboot getvar at-vboot-state', then HANG
in the fastboot without any message.

Cause: The fastboot can not decide the vboot size when
the return information size of vboot state is larger
than the VBOOT_STATE_SIZE. This makes the device will not
response to console.

Solution: 1. Enlarge VBOOT_STATE_SIZE. The max size of
vboot state may be 862, so define VBOOT_STATE_SIZE
to 1000.
2. Use snprintf to get the info.

Jason Zhu df50318e9d lib: avb: add slot number to avb-min-versions 
Acording to google, the avb-min-versions includes the slot number
rather than the image rollback-index stored in the image.

PIK/PSK: use AVB_ATX_PSK_VERSION_LOCATION and AVB_ATX_PIK_VERSION_LOCATION
as slot number.
