west: runners: nrf: don't recover twice on nrf54h



Update the recover mechanism for nrf54h to only call recover
once. Using nrfutil device recover with both --core Network and
--core Application is redundant with IronSide SE as both of these
map to the same operation which does a full erase of the device MRAM.

Additionally, recovering twice in a row specifically in a nrfutil
batch file (which is used by this runner implementation) triggers some
odd behavior with the current latest version of
nrfutil device + IronSide SE, which can cause the device to enter a
reset loop and appear unresponsive and preventing 'west flash --recover'
from working properly.
