I/OAT: fixups from code comments

A few fixups from Andrew's code comments.
  - removed "static inline" forward-declares
  - changed use of min() to min_t()
  - removed some unnecessary NULL initializations
  - removed a couple of BUG() calls

Fixes this:

drivers/dma/ioat_dma.c: In function `ioat1_tx_submit':
drivers/dma/ioat_dma.c:177: sorry, unimplemented: inlining failed in call to '__ioat1_dma_memcpy_issue_pending': function body not available
drivers/dma/ioat_dma.c:268: sorry, unimplemented: called from here
