[PATCH 2/3] mtd: rawnand: denali: Remove always true test

[Andrew Goodbody]

In denali_wait_for_irq the code will either return from inside the while
loop or exit with time_left being 0. The following test for time_left
being 0 is guranteed to be true so remove the test and the following
unreachable code.

This issue was found by Smatch.
