Set Cert: should not check BasicConstraint CA: True with hardcoded value

[rw8896]

libspdm/library/spdm_crypt_lib/libspdm_crypt_cert.c

Lines 840 to 846 in b327ead

	/*alias cert model*/
	if (status && (len == sizeof(basic_constraints_true_case)) &&
	(libspdm_consttime_is_mem_equal(cert_basic_constraints,
	basic_constraints_true_case,
	sizeof(basic_constraints_true_case)))) {
	return true;
	}

Device Cert could specify pathLenConstraint in BasicConstraints and hence the hardcoded BASIC_CONSTRAINTS_STRING_TRUE_CASE can't cover all the true cases.

Line 98 in b327ead

#define BASIC_CONSTRAINTS_STRING_TRUE_CASE {0x30, 0x03, 0x01, 0x01, 0xFF}

Presumably the call to libspdm_x509_get_extended_basic_constraints would fail as cert_basic_constraints is not large enough to hold the whole field.
