After commit 956db0a13b47 ("net: warn about attempts to register
negative ifindex") syzbot is able to trigger the following splat.
Negative ifindex are not supported.

Shouldn't this be <= 0 since 0 is not a valid ifindex.
Zero ifindex is used as a sentinel in some API's
For example: if_nametoindex() returns 0 if name is not found.

Setting tfile->ifindex to zero should be a NOP ?
This means dev_index_reserve() will allocate a ifindex for us.
Not sure we want to prevent something that was working properly in the past.
