HID: core: do not allow parsing 0-sized reports
Commit d7db259bd6df ("HID: core: factor out hid_parse_collections()")
reworked collection parsing code and inadvertently allowed returning
"success" when parsing 0-sized reports where old code returned -EINVAL.
Restore the original behavior by doing an explicit check.
Note that the error message now differs from the generic "item fetching
failed at offset %u/%u" that is now used only for non-empty descriptors.
Fixes: d7db259bd6df ("HID: core: factor out hid_parse_collections()")
