Takashi Iwai 8293705696 usb: gadget: midi2: Fix interpretation of is_midi1 bits ...

The UMP Function Block info m1.0 field (represented by is_midi1 sysfs
entry) is an enumeration from 0 to 2, while the midi2 gadget driver
incorrectly copies it to the corresponding snd_ump_block_info.flags
bits as-is.  This made the wrong bit flags set when m1.0 = 2.

This patch corrects the wrong interpretation of is_midi1 bits.
