[LU-9611] fix default stripe count/offset proc tunables

Duplicate — Mon, 26 Mar 2018 17:55:44 +0000

Since patch http://review.whamcloud.com/16930 "LU-7334 lprocfs: Refactored string to value helpers" was landed, it incorrectly checks that lod.*.stripecount and lod.*.stripeoffset are not negative, but in fact they can both be "-1" to indicate that the filesystem-wide default value should be used. These parameters are also set internally if using lfs setstripe -c -1 $MOUNT or lfs setstripe -i -1 $MOUNT to set the system wide default, generating a console error on the MDS:

LustreError: 12558:0:(obd_config.c:1392:class_process_proc_param())  lov.: error writing proc entry 'stripecount': rc = -34
LustreError: 12558:0:(obd_config.c:1392:class_process_proc_param())  lov.: error writing proc entry 'stripeoffset': rc = -34
