mtd: rawnand: brcmnand: Fix potential false time out warning
Backport from the Linux kernel:
commit 9cc0a598b944816f2968baf2631757f22721b996
"mtd: rawnand: brcmnand: Fix potential false time out warning"
If system is busy during the command status polling function, the driver
may not get the chance to poll the status register till the end of time
out and return the premature status. Do a final check after time out
happens to ensure reading the correct status.
