Subject: x509asn1: Silence x64 loss-of-data warning on RSA key length assignment
X-Git-Tag: curl-7_42_0~45

x509asn1: Silence x64 loss-of-data warning on RSA key length assignment

The key length in bits will always fit in an unsigned long so the
loss-of-data warning assigning the result of x64 pointer arithmetic to
an unsigned long is unnecessary.
