f2fs: Fix not used variable 'index'

[ Upstream commit 0c3a38a4b442893f8baca72e44a2a27d52d6cc75 ]

Fix the following compilation warning:
fs/f2fs/data.c:2391:10: warning: variable ‘index’ set but not used
[-Wunused-but-set-variable]
 2391 |  pgoff_t index;

Only define and set the variable index when the CONFIG_F2FS_FS_COMPRESSION
is enabled.
