HID: fix bug in zeroing the last field byte in output reports
d4ae650a904612ffb7edd3f28b69b022988d2466 introduced zeroing of the last field byte in output reports in order to make sure the unused bits are set to 0. This is done in a wrong way, resulting in a wrong bits being zeroed out (not properly shifted by the field offset in the report). Fix this. Signed-off-by: Jiri Kosina <jkosina@suse.cz>
