Subject: [PATCH] ext4: delete unused mapping variable

The code refactoring in commit "ext4: refactor punch hole code"
left behind a now unused variable, causing:

fs/ext4/inode.c: In function ‘ext4_punch_hole’:
fs/ext4/inode.c:3495:24: warning: unused variable ‘mapping’ [-Wunused-variable]

Signed-off-by: Paul Gortmaker <paul.gortmaker@...driver.com>

[Feel free to also fold this trivial change back into the original
punch hole commit on the dev branch]
