iio: buffer-dmaengine: use %zu specifier for sprintf(align)



The 'size_t' type behaves differently on 64-bit architectures, and causes
compiler a warning of the sort "format '%u' expects argument of type
'unsigned int', but argument 3 has type 'size_t {aka long unsigned int}'".

This change adds the correct specifier for the 'align' field.
