ALSA: usb-audio: Fix regression on detection of Roland VS-100

commit fa4e7a6fa12b1132340785e14bd439cbe95b7a5a upstream.

It's been reported that the recent kernel can't probe the PCM devices
on Roland VS-100 properly, and it turned out to be a regression by the
recent addition of the bit shift range check for the format bits.
In the old code, we just did bit-shift and it resulted in zero, which
is then corrected to the standard PCM format, while the new code
explicitly returns an error in such a case.

For addressing the regression, relax the check and fallback to the
standard PCM type (with the info output).
