vboot: check vb2_shared_data flags for manual recovery
vboot handoff should look at flags in struct vb2_shared_data when translating flags to VBSD_BOOT_REC_SWITCH_ON because VBSD_BOOT_REC_SWITCH_ON is supposed to indicate whether manual recovery was triggered or not while vb2_sd->recovery_reason will be able to provide that information only in some cases after CL:307586 is checked in. For example, this fixes a recovery loop problem: Without this fix, vb2_sd->recovery_reason won't be set to VB2_RECOVERY_RO_MANUAL when user hits esc+refresh+power at 'broken' screen. In the next boot, recovery_reason will be set to whatever reason which caused 'broken' screen. So, if we check recovery_reason == VB2_RECOVERY_RO_MANUAL, we won't set vb_sd->flags to VBSD_BOOT_REC_SWITCH_ON. That'll cause a recovery loop because VbBootRecovery traps us again in the 'broken' screen after not seeing VBSD_BOOT_REC_SWITCH_ON.
