No check on return value of ASN1_item_ndef_i2d() #14177
Description
In crypto/asn1/bio_ndef.c, line 116 in ndef_prefix(), the return value derlen of ASN1_item_ndef_i2d does not get checked. However, it could be smaller than 0.
I wonder whether the right handling should check derlen<=0 before proceed.
