[Michel Dänzer]

From: Michel Dänzer <michel.daenzer at amd.com>

Pointed out by clang:

../../src/radeon_kms.c:1562:6: warning: variable 'total_size_bytes' is uninitialized when used here [-Wuninitialized]
            total_size_bytes += (64 * 4 * 64);
            ^~~~~~~~~~~~~~~~
../../src/radeon_kms.c:1557:25: note: initialize the variable 'total_size_bytes' to silence this warning
    int total_size_bytes;
                        ^
                         = 0
