[PATCH] driver: nvme: fix missing error code

[Dongliang Mu]

Smatch reports:

drivers/nvme/host/multipath.c:865
nvme_mpath_init_identify() warn: missing error code 'error'

In one error handling path of nvme_mpath_init_identify(Line 865), error
is not initialized as an errno.

Fix this by assigning error to -EINVAL.
