jfs: Fix uninit-value access of newea in eabuffer

syzbot reports that lzo1x1docompress is using uninit-value:

===================================================== BUG: KMSAN: uninit-value in lzo1x1docompress+0x19f9/0x2510 lib/lzo/lzo1xcompress.c:178

...

Uninit was stored to memory at: eaput fs/jfs/xattr.c:639 [inline]

...

Local variable eabuf created at: jfssetxattr+0x5d/0x1ae0 fs/jfs/xattr.c:662 jfsxattrset+0xe6/0x1f0 fs/jfs/xattr.c:934

=====================================================

The reason is eabuf->newea is not initialized properly.

Fix this by using memset to empty its content at the beginning in eaget().
