[PATCH] CRED: fix compilation warning in function 'get_cred'

[Hannes Eder]

Fix to following warning by introducing a temporary variable:

include/linux/cred.h: In function 'get_cred':
include/linux/cred.h:187: warning: passing argument 1 of
'get_new_cred' discards qualifiers from pointer target type

With -O2 the same code as for the original function is generated.
