        src/sys/dev/pci/ixgbe: if_bypass.c

Log Message:
Fix checking return value of atomic_cas_uint().

This change fixes a bug that extra delay() is called only once even if
atomic_cas_uint() isn't failed or delay() isn't called when atomic_cas_uint()
failed.

The reason of this bug was that I simply converted FreeBSD' atomic_cmpset_int()
to atomic_cas_uint(). The return value's semantics is different.
