mmc: atmel-mci: fix mismatched section on atmci_cleanup_slot

Browse Source 
As of 528bc7808f ("mmc: atmel-mci: Release mmc resources on failure in probe"),
the atmci_probe() function calls atmci_cleanup_slot in the failure path.

This causes a new warning whenever the driver is built:

WARNING: drivers/mmc/host/built-in.o(.init.text+0xa04): Section mismatch in reference from the function atmci_probe() to the function .exit.text:atmci_cleanup_slot()
The function __init atmci_probe() references
a function __exit atmci_cleanup_slot().

Gcc correctly warns about this function getting dropped in the link stage
for the built-in case, which would cause undefined behavior when this error
path is hit. The solution is to simply drop the __exit annotation.
