mtd: nand: omap: fix race condition in omap_wait()
If a context switch occurs in function omap_wait() just before the while loop is entered, then upon return from context switch the timeout may already have elapsed: in that case, status is never read from NAND device, and omap_wait() returns an error. This failure has been experimentally observed during stress tests. This patch ensures a NAND status read is always performed before returning, as in the generic nand_wait() function.
