USB: serial: digi_acceleport: fix OOB data sanity check
commit 2d380889215fe20b8523345649dee0579821800c upstream.
Make sure to check for short transfers to avoid underflow in a loop
condition when parsing the receive buffer.
Also fix an off-by-one error in the incomplete sanity check which could
lead to invalid data being parsed.
Fixes: 8c209e6782ca ("USB: make actual_length in struct urb field u32")
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
