Input: iforce - invert valid length check when fetching device IDs

In the Linux kernel, the following vulnerability has been resolved:

Input: iforce - invert valid length check when fetching device IDs

syzbot is reporting uninitialized value at iforce_init_device() [1], for

commit 6ac0aec6b0a6 ("Input: iforce - allow callers supply data buffer

when fetching device IDs") is checking that valid length is shorter than

bytes to read. Since iforce_get_id_packet() stores valid length when

returning 0, the caller needs to check that valid length is longer than or

equals to bytes to read.
