Chao Yu 872340aa04 f2fs: fix potential overflow 
commit 1f0d5c911b64165c9754139a26c8c2fad352c132 upstream.

We expect 64-bit calculation result from below statement, however
in 32-bit machine, looped left shift operation on pgoff_t type
variable may cause overflow issue, fix it by forcing type cast.

page->index << PAGE_SHIFT;

Fixes: 26de9b1171 ("f2fs: avoid unnecessary updating inode during fsync")
Fixes: 0a2aa8fbb9 ("f2fs: refactor __exchange_data_block for speed up")
