nfc: st21nfca: fix incorrect validating logic in EVT_TRANSACTION

stable inclusion
from stable-v5.10.122
commit 4f0a2c46f588e09b37b831f78f9015463a4b21b6
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I5W6OE

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=4f0a2c46f588e09b37b831f78f9015463a4b21b6



--------------------------------

commit 77e5fe8f upstream.

The first validation check for EVT_TRANSACTION has two different checks
tied together with logical AND. One is a check for minimum packet length,
and the other is for a valid aid_tag. If either condition is true (fails),
then an error should be triggered.  The fix is to change && to ||.
