The PreSonus AudioBox USB (0x194f:0x0301) only supports S24_3LE
format for both playback and capture. It does not support S16_LE
despite being a USB full-speed device. Add explicit format quirks
for both the playback (interface 2) and capture (interface 3)
interfaces to ensure correct format negotiation.

v2: Fix placement -  entry was incorrectly inside a #if 0 disabled block.
Moved to after the #endif /* disabled */.

The patch description doesn't match with what you actually change
here.  Also, as it's a correction, it should have a Fixes tag.
Please update the description and resubmit.
