[PATCH 5/9] namespaces: utsname: use init_utsname when appropriate

["Serge E. Hallyn" <serue@us.ibm.com>]

In some places, particularly drivers and __init code, the init utsns is the
appropriate one to use.  This patch replaces those with a the init_utsname
helper.

Changes: Removed several uses of init_utsname().  Hope I picked all the
	right ones in net/ipv4/ipconfig.c.  These are now changed to
	utsname() (the per-process namespace utsname) in the previous
	patch (2/7)

Signed-off-by: Serge E. Hallyn <serue@us.ibm.com>
