Junrui Luo 0c4a13ba88 ALSA: wavefront: Fix integer overflow in sample size validation ...

The wavefront_send_sample() function has an integer overflow issue
when validating sample size. The header->size field is u32 but gets
cast to int for comparison with dev->freemem

Fix by using unsigned comparison to avoid integer overflow.
