[LU-12169] Assertion on mdc_pack_name

• Status: Resolved
• Project: Lustre
• Fix Version/s: Lustre 2.13.0, Lustre 2.12.3
• Type: Bug

• Resolution: Fixed
• Severity: 3

Description

If some race happen, dentry name which we copied is invalid,
we should return failure directly rather than continue.

Because Server doesn't support open-by-fid, we pass @name
as NULL, @len as 0, it will definitely trigger following
assertion in mdc_pack_name()

LustreError: 157839:0:(mdc_lib.c:137:mdc_pack_name()) LBUG
