ALSA: wavefront: Fix integer overflow in sample size validation
commit 0c4a13ba88594fd4a27292853e736c6b4349823d upstream.
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.
