Kunwu Chan 98e2b97acb pstore/zone: Add a null pointer check to the psz_kmsg_read ...

[ Upstream commit 98bc7e26e14fbb26a6abf97603d59532475e97f8 ]

kasprintf() returns a pointer to dynamically allocated memory
which can be NULL upon failure. Ensure the allocation was successful
by checking the pointer validity.
