IOCTLs causing firmware fault may end up in failed controller resets and
finally killing the adapter.

This patch fixes this problem as stated below:

In OCR sequence, driver will attempt refiring pended IOCTLs upto two times.
If first two attempts fail, then in third attempt driver will return pended
IOCTLs with EBUSY status to application. These changes are done to ensure
if any of pended IOCTLs is causing firmware fault and resulting into OCR
failure, then in last attempt of OCR driver will refrain firing it to
firmware and saving adapter from being killed due to faulty IOCTL.
