Yang Yingliang 09776d9374 iio: buffer: Fix double-free in iio_buffers_alloc_sysfs_and_mask() 
When __iio_buffer_alloc_sysfs_and_mask() failed, 'unwind_idx' should be
set to 'i - 1' to prevent double-free when cleanup resources.

BUG: KASAN: double-free or invalid-free in __iio_buffer_free_sysfs_and_mask+0x32/0xb0 [industrialio]
Call Trace:
 kfree+0x117/0x4c0
