drm/amd/powerplay: Fix buffer overflows with mc_reg_address

2017-12-06T17:48:00Z

Smatch warned about the following lines: ci_set_mc_special_registers() error: buffer overflow 'table->mc_reg_address' 16 <= 16 tonga_set_mc_special_registers() error: buffer overflow 'table->mc_reg_address' 16 <= 16 Change the logic to check before access instead of after incrementing. It's fine if j reaches max after we're done. This allows the last entry of the array to be filled without an error message for example. Changed some whitespace to clarify grouping.
