Commit
3862828a903d3 ("iio: buffer: Switch to bitmap_zalloc()") introduced
bitmap_alloc(), but commit
20ea39ef9f2f9 ("iio: Fix scan mask selection")
reverted it.
This change adds it back. The only difference is that it's adding
bitmap_zalloc(). There might be some changes later that would require
initializing it to zero. In any case, now it's already zero-ing the
trialmask.
Appears to have been the result of merge conflict resolution rather
than an intentional revert.
