[PATCH] keys: asymmetric: fix error return code in software_key_query()

[David Howells]

From: Wei Yongjun <weiyongj...@huawei.com>

Fix to return negative error code -ENOMEM from kmalloc() error handling
case instead of 0, as done elsewhere in this function.

Fixes: f1774cb8956a ("X.509: parse public key parameters from x509 for 
akcipher")
