comedi: vmk80xx: fix bulk-buffer overflow
commit 78cdfd62bd54af615fba9e3ca1ba35de39d3871d upstream.
The driver is using endpoint-sized buffers but must not assume that the
tx and rx buffers are of equal size or a malicious device could overflow
the slab-allocated receive buffer when doing bulk transfers.
