sysfs: Rename struct bin_attribute member to f_mapping 

There are two users of iomem_get_mapping(), the struct file and struct
bin_attribute.  The former has a member called "f_mapping" and the
latter has a member called "mapping", and both are poniters to struct
address_space.

Rename struct bin_attribute member to "f_mapping" to keep both meaning
and the usage consistent with other users of iomem_get_mapping().
