Subject: [PATCH v3] Staging: vc04_services: Cleanup in ctrl_set_bitrate()

Remove unnecessary variable from the function and make a corresponding
change w.r.t the variable. In addition to that align the parameters in
the parentheses to maintain Linux kernel coding style

Issue suggested by Coccinelle.

Signed-off-by: Madhumitha Prabakaran <madhumithabiw@...il.com>

---
Changes in v2 -
1) Fix my own error of removing function call from the variable.
2) Align the function parameters with parentheses.

Changes in v3 -
1) Since there was no real purpose of returning true value, replace it with
return value of the function vchiq_mmal_port_parameter_set().
