spa_taskq_dispatch_ent: simplify arguments

Browse Source 
This renames it to spa_taskq_dispatch(), and reduces and simplifies its
arguments based on these observations from its two call sites:

- arg is always the zio, so it can be typed that way, and we don't need
  to provide it twice;
- ent is always &zio->io_tqent, and zio is always provided, so we can
  use it directly;
- the only flag used is TQ_FRONT, which can just be a bool;
- zio != NULL was part of the "use allocator" test, but it never would
  have got that far, because that arg was only set to NULL in the
  reexecute path, which is forced to type CLAIM, so the condition would
  fail at t == WRITE anyway.
