In commit '7d7ea89e756e', pass the 3rd param of trace_ext4_ext_load_extent
to _RET_IP, without modifying the print-format of it.
before this:
147.827896: ext4_ext_load_extent: dev 8,35 ino 272218 lblk 1135807 pblk 18446744072651077338
after this:
35.118227: ext4_ext_load_extent: dev 8,35 ino 272218 pblk 1135807 caller ext4_find_extent+0x17a/0x320 [ext4]
Fixes: 7d7ea89e756e ("ext4: refactor code to read the extent tree block")
