openssl: return -1 on error in the BIO callbacks

BIO_read and BIO_write return negative numbers on error, including
retryable ones. A regression from 55807e6. Both branches should be
returning -1.

The APIs are patterned after POSIX read and write which, similarly,
return -1 on errors, not zero, with EAGAIN treated as an error.
