In order to make the entire kernel usable under Clang's Control Flow
Integrity protections, function prototype casts need to be avoided
because this will trip CFI checks at runtime (i.e. a mismatch between
the caller's expected function prototype and the destination function's
prototype). Many of these cases can be found with -Wcast-function-type,
which found that the rtl wifi drivers had a bunch of needless function

The local variable 'bcmd_down' is always set to true almost immediately
before the do-while's condition is checked. As a result, !bcmd_down
evaluates to false which short circuits the logical AND operator meaning
that the second operand is never reached and is therefore dead code.
Furthermore, the do..while loop may be removed since it will always only
execute once because 'bcmd_down' is always set to true, so the
!bcmd_down evaluates to false and the loop exits immediately after the
first pass.
Fix this by removing the loop and its condition variables 'bcmd_down'
and 'retry_cnts'

This code generates checkpatch warning:
WARNING: else is not generally useful after a break or return
Moving the declaration to the top of the function we can pull the
code back one tab and it makes it more readable.

Variable rtstatus is being initialized with a value that is never read
and rtstatus is being re-assigned a little later on. The assignment is
redundant and hence can be removed. Also, make rtstatus a bool to
match the function return type.
