ARM: Fix get_cycles() after delay_read_timer() conversion

After commit dfc256dac5 ("calibrate: Rework delay timer calibration"),
certain ARM configurations (such as multi_v5_defconfig) hang during
boot. The use of read_current_timer() in arch/arm's get_cycles() was
improperly converted to delay_read_timer(), resulting in get_cycles()
returning 0 even when the timer has been read or an uninitialized stack
value when delay_read_timer() returns false.

Flip the branches of the ternary condition to fix get_cycles().
