Fix a const pointer usage warning in the Digigram VX soundcard driver

Fix a const pointer usage warning in the Digigram VX soundcard driver.  A
const pointer is being passed to copy_from_user() to load the firmware into.
This is okay in this case because the function has allocated the firmware
struct itself, but the const qualifier will be part of the firmware
struct - so the patch casts the const away.
