[PATCH 5.6 136/166] ext2: fix debug reference to ext2_xattr_cache

[ Upstream commit 32302085a8d90859c40cf1a5e8313f575d06ec75 ]

Fix a debug-only build error in ext2/xattr.c:

When building without extra debugging, (and with another patch that uses
no_printk() instead of <empty> for the ext2-xattr debug-print macros,
this build error happens:

../fs/ext2/xattr.c: In function âext2_xattr_cache_insertâ:
../fs/ext2/xattr.c:869:18: error: âext2_xattr_cacheâ undeclared (first use in
this function); did you mean âext2_xattr_listâ?
atomic_read(&ext2_xattr_cache->c_entry_count));

Fix the problem by removing cached entry count from the debug message
since otherwise we'd have to export the mbcache structure just for that.
