usb: ks_bridge: Limit write size to 16KB

The user space application writes in 1MB chunks while loading MDM
images.  The current code allocate as many bytes as user space
passed to write system call.  These allocations are failing under
memory fragmentation scenario.  Hence limit write size to 16KB.
