Fix minor inconsistency in connFormatAddr size argument (#14731)

**Type**: Refactoring / Code Cleanup

**Description**: While reviewing the connection layer logic, I noticed a
minor inconsistency in how buffer sizes are passed to `connFormatAddr`.

In the error handling block of `acceptCommonHandler`, `sizeof(addr)` is
currently used for both the remote address and the local address
buffers. While both addr and laddr are defined with the same size
(`NET_ADDR_STR_LEN`), it is more idiomatic and safer to use the sizeof
of the actual buffer being populated.

**This change ensures:**
- Defensive Programming: Prevents potential buffer overflows or
truncation issues if the array sizes are changed independently in the
future.
- Code Clarity: Removes ambiguity for future maintainers and ensures the
logic is self-consistent.
