Kernel: Initialize DiskCache's buffer before the dirty&clean lists
This commit fixes a kernel panic that happened when unmounting
a disk due to an invalid memory access.
This was because `DiskCache` initializes two linked lists that use
an argument `KBuffer` as the storage for their elements.
Since the member `KBuffer` was declared after the two lists,
when `DiskCache`'s destructor was called, then `KBuffer`'s destructor
was called before the ones of the two lists, causing a page fault in
the kernel.
