Randall Huang 5811f24abd f2fs: fix to avoid memory leakage in f2fs_listxattr
commit 688078e7f36c293dae25b338ddc9e0a2790f6e06 upstream.

In f2fs_listxattr, there is no boundary check before
memcpy e_name to buffer.
If the e_name_len is corrupted,
unexpected memory contents may be returned to the buffer.
