The two functions check_wipe_package() and check_newer_ab_build() were using the same flow; and checked the same device properties against the metadata file in the package. These properties include: ota_type, pre-device, and serial number. Therefore, we can consolidate the checks to a single function; and continue to check the fingerprint and timestamp only for AB updates. This change also addresses the need to accept multiple serial number in the wipe package. Bug: 118401208 Test: unit tests pass Change-Id: Ia6bc48fb6effcae059a2ff2cf71764b4136b4c00
