[PATCH] creds: suppress warning in get_cred

[Stephen Rothwell <sfr@canb.auug.org.au>]

This is the usual way to force a conversion from a const pointer to a
non-const one and gets rid of this warning:

include/linux/cred.h: In function 'get_cred':
include/linux/cred.h:188: warning: passing argument 1 of 'get_new_cred' discards qualifiers from pointer target type
