Subject: [PATCH] fs: fix ext4 unused-variable warning

A bugfix introduce a harmless warning:

fs/ext4/inode.c: In function 'ext4_page_mkwrite':
fs/ext4/inode.c:5910:24: error: unused variable 'mapping' [-Werror=unused-variable]

Remove the now-unused variable.

Fixes: 4a58d8158f6d ("fs: Fix page_mkwrite off-by-one errors")
