psa: Remove buggy report of RSA public exponent for opaque keys

Browse source 
The report of RSA public exponent for opaque keys is not
supported. Do not attempt to compute the RSA public
exponent of an RSA opaque key associated to a driver
implementing the new driver interface when
MBEDTLS_PSA_CRYPTO_SE_C is disabled.
