iavf: simplify mutex_trylock+sleep loops

This pattern appears in two places in the iavf source code:
  while (!mutex_trylock(...))
      usleep_range(...);

That's just mutex_lock with extra steps.
The pattern is a leftover from when iavf used bit flags instead of
mutexes for locking. Commit 5ac49f3c2702 ("iavf: use mutexes for locking
of critical sections") replaced test_and_set_bit with !mutex_trylock,
preserving the pattern.

Simplify it to mutex_lock.
