From: Chengyu Zhu <hudson...@tencent.com>
The erofs_nbd_get_identifier() function returns dynamically allocated
memory via getline(), but the caller in erofsmount_nbd() was not
freeing this memory, causing a 120-byte memory leak.
Add proper memory cleanup by calling free(id) when the identifier
is not an error pointer.
