pcmcia: Use resource_size function on resource object

Browse Source 
[ Upstream commit 24a025497e7e883bd2adef5d0ece1e9b9268009f ]

Cocinnele reports a warning

WARNING: Suspicious code. resource_size is maybe missing with root

The root cause is the function resource_size is not used when needed

Use resource_size() on variable "root" of type resource
