FS-Cache: Add missing initialization of ret in cachefiles_write_page()

Browse source 
fs/cachefiles/rdwr.c: In function ‘cachefiles_write_page’:
fs/cachefiles/rdwr.c:882: warning: ‘ret’ may be used uninitialized in
this function

If the jump to label "error" is taken, "ret" will indeed be
uninitialized, and random stack data may be printed by the debug code.

Fixes: 102f4d900c ("FS-Cache: Handle a write to the page immediately beyond the EOF marker")
