fs/pstore: update the backend parameter in pstore module
This patch update the module parameter backend, so it is visible
through /sys/module/pstore/parameters/backend.
For example:
if pstore backend is ramoops, with this patch:
# cat /sys/module/pstore/parameters/backend
ramoops
and without this patch:
# cat /sys/module/pstore/parameters/backend
(null)
