[PATCH] staging: rtl8723bs: core: Remove variable priority

[Nishka Dasgupta]

Remove local variable change_priority, as it takes the value of the
argument priority; as both of these variables are of type u8, priority
can be modified without changing the value of its copy at the call site.
Issue found with Coccinelle.
