Subject: zlogger: Fix int-conversion error with gcc-14
X-Git-Tag: accepted/tizen/unified/toolchain/20240610.173225^0

zlogger: Fix int-conversion error with gcc-14

It's failed because of type casting as  unsigned long.
p is already pointer type, so it doesn't need to cast.
- It can already notice as warning with gcc13.
