[PATCH] staging: rtl8723bs: use inline functions for dev_to_sdio_func

[Menna Mahmoud]

Convert `dev_to_sdio_func` macro into a static inline function.
it is not great to have macro that use `container_of` macro,
because from looking at the definition one cannot tell
what type it applies to.

One can get the same benefit from an efficiency point of view
by making an inline function.
