bswap: Modify prototype of stb_p (avoid type conversions)

Browse source 
The function uses an uint8_t value, so show this in the function
prototype. Non-optimizing compilers will avoid unnecessary type
conversions from (u)int8_t to int and back to uint8_t when generating
calls of this inline function.

stw_p, stl_p and stq_p already use similar prototypes.
