firmware/2lib: Remove redundant EC sync check in recovery

This patch removes the redundant EC sync check in recovery mode.
The check is already performed by vb2api_ec_sync, the caller of
`ec_sync_phase2`/`ec_sync_phase1`.

This change also allows ec_sync_allowed to be used by `ec_sync_phase1`
to ensure EC sync prerequisites are met.
