s390/zcrypt: Avoid alloc and copy of ep11 targets if kernelspace cprb
If there is a target list of APQNs given when an CPRB is
to be send via zcrypt_send_ep11_cprb() there is always a
kmalloc() done and the targets are copied via z_copy_from_user.
As there are callers from kernel space (zcrypt_ep11misc.c)
which signal this via the userspace parameter improve this
code to directly use the given target list in case of
kernelspace thus removing the unnecessary memory alloc
and mem copy.
