scd:ccid:spr532: Extend abort_cmd for initialization time.
* scd/ccid-driver.c (abort_cmd): Add INIT argument to support synchronize until success, even ignoring timeout. (bulk_in): Normal use case of abort_cmd. (ccid_vendor_specific_init): Initial use case of abort_cmd. Signed-off-by: NIIBE Yutaka <gniibe@fsij.org>
