anv: Fix transfer type assert

Fix defect reported by Coverity Scan.

Constant expression result (CONSTANT_EXPRESSION_RESULT)
always_true_or: The or condition
type != ANV_TIMESTAMP_CAPTURE_AT_CS_STALL || type != ANV_TIMESTAMP_REWRITE_COMPUTE_WALKER
will always be true because type cannot be equal to two different values
at the same time, so it must be not equal to at least one of them.
