[PATCH 5.16 0959/1039] crypto: octeontx2 - uninitialized variable in kvf_limits_store()

[Greg Kroah-Hartman]

From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

commit 0ea275df84c389e910a3575a9233075118c173ee upstream.

If kstrtoint() fails then "lfs_num" is uninitialized and the warning
doesn't make any sense.  Just delete it.

Fixes: 8ec8015a3168 ("crypto: octeontx2 - add support to process the crypto request")
