Double clear of reset requested state can lead to NULL pointer as it
will try to delete the timer twice. This can happen for example on a
race between abort from FW and pci error or reset. Avoid such case using
test_and_clear_bit() to verify only one time reset requested state clear
flow. Similarly use test_and_set_bit() to verify only one time reset
requested state set flow.
