OvmfPkg: QemuFlashFvbServicesRuntimeDxe: rewrap source code to 79 chars

Some of the line lengths in this driver are atrocious. While we have to
put up with the status quo outside of OvmfPkg, we can at least rewrap this
driver before refactoring it.

In the FvbInitialize() function there's no way around introducing two
local variables, just for the sake of sensibly rewrapping the code.

Furthermore, in "FwBlockService.c" the function comment blocks are now
indented; their original position causes diff to print bogus function
names at the top of hunks.
