It's normal behavior if you're using something like NetworkManager,
which monitors interfaces coming up/going down and performs actions
(like reassociating and getting a new DHCP lease) in response.
My intuition is that moving to MMC_PM_KEEP_POWER is probably overkill
for you, and instead you'll just want to reset the card across suspend
and tell userspace to reconnect to the previous AP after it comes back
