Subject: [PATCH 3/4] ext4: adjust the debug info in ext4_es_cache_extent()

From: Zhang Yi <yi.zhang@...wei.com>

Print a trace point after successfully inserting an extent in the
ext4_es_cache_extent() function. Additionally, similar to other extent
cache operation functions, call ext4_print_pending_tree() to display the
extent debug information of the inode when in ES_DEBUG mode.
