ALSA: xen-front: fix unintention integer overflow on left shifts
Shifting the integer value 1 is evaluated using 32-bit
arithmetic and then used in an expression that expects a 64-bit
value, so there is potentially an integer overflow. Fix this
by using the BIT_ULL macro to perform the shift.
[ Note: as of the time being, no actual integer overflow hits because
all values are less than 32bit, not including the extended 3-byte or
DSD formats. But this is the right fix for future usage, of
course. -- tiwai ]
