mmc: core: Handle err variable properly in shutdown path

Browse source 
issue: "mmc0: error -22 during shutdown" logs seen
in shutdown path.

Initially the err variable is initialized with -EINVAL(22)
Before shutting down the eMMC, it make sure that eMMC
should be in active state, in order to do so
 _mmc_resume will be called in mmc_shutdown.

Since the device is already in active state it returns
from the suspend if check and returns -22 to the
mmc_shutdown and treat as error.

Making err variable 0 in the if check will help to
resolve this issue.
