log: initialize pos to help the compiler

Browse source 
Although pos will be set to 0 in the first iteration, the compiler does
not seem to figure this out, so help it a little:

../spa/include/spa/support/log.h:306:21: warning: ‘pos’ may be used uninitialized [-Wmaybe-uninitialized]
  306 |                 pos += sprintf(str + pos, "%02x ", buf[i]);                             \
      |                     ^~
../spa/include/spa/support/log.h:301:13: note: ‘pos’ was declared here
  301 |         int pos;                                                                        \
      |             ^~~
