[PATCH v4 4/9] crypto/nx: Initialize coproc entry with kzalloc

coproc entry is initialized during NX probe on power9, but not on P8.
nx842_delete_coprocs() is used for both and frees receive window if it
is allocated. Getting crash for rmmod on P8 since coproc->vas.rxwin
is not initialized.

This patch replaces kmalloc with kzalloc in nx842_powernv_probe()
