[PATCH] integrity: use KERNEL_DS instead of get_ds()

[Jann Horn]

get_ds() is a legacy name for KERNEL_DS; all architectures #define it to
KERNEL_DS, and almost every user of set_fs() uses the name KERNEL_DS.

Let the integrity subsystem also use KERNEL_DS so that we can get rid of
get_ds() at some point.
