rtlwifi: rtl8192ce: Fix incorrect returned values

In commit 98fd8db5 ("rtlwifi: rtl8192ce: Convert macros that set
descriptor"), all the routines that get fields from a descriptor
were changed to return signed integer values. This is incorrect for the
routines that get the entire 32-bit word. In this case, an unsigned
quantity is required.
