[PATCH] afs: hide a new unused variable

[Arnd Bergmann]

The buld readpages support introduced a harmless warning:

fs/afs/file.c: In function 'afs_readpages_page_done':
fs/afs/file.c:270:20: error: unused variable 'vnode' [-Werror=unused-variable]

This adds an #ifdef to match the user of that variable.

Fixes: 91b467e0a3f5 ("afs: Make afs_readpages() fetch data in bulk")
