fs/ntfs3: Don't clear upper bits accidentally in log_replay()

Browse Source 
commit 926034353d3c67db1ffeab47dcb7f6bdac02a263 upstream.

The "vcn" variable is a 64 bit.  The "log->clst_per_page" variable is a
u32.  This means that the mask accidentally clears out the high 32 bits
when it was only supposed to clear some low bits.  Fix this by adding a
cast to u64.
