KEYS: Reinstate lost passing of process keyring ID in call_sbin_request_key()

In commit bb952bb9 there was the accidental
deletion of a statement from call_sbin_request_key() to render the process
keyring ID to a text string so that it can be passed to /sbin/request-key.

With gcc 4.6.0 this causes the following warning:

  CC      security/keys/request_key.o
security/keys/request_key.c: In function 'call_sbin_request_key':
security/keys/request_key.c:102:15: warning: variable 'prkey' set but not used

This patch reinstates that statement.

Without this statement, /sbin/request-key will get some random rubbish from the
stack as that parameter.
