HID: bigben_worker() remove unneeded check on report_field
bigben_worker() checks report_field to be non-NULL.
The check has been added in commit
918aa1ef104d ("HID: bigbenff: prevent null pointer dereference")
to prevent a NULL pointer crash.
However, the true root cause was a missing check for output
reports, patched in commit
c7bf714f8755 ("HID: check empty report_list in bigben_probe()"),
where the type-confused report list_entry was overlapping with
a NULL pointer, which was then causing the crash.
Fixes: 918aa1ef104d ("HID: bigbenff: prevent null pointer dereference")
