initrd: remove the BLKFLSBUF call in handle_initrd
BLKFLSBUF used to be overloaded for the ramdisk driver to free the whole
ramdisk, which was completely different behavior compared to all other
drivers. But this magic overload got removed in commit ff26956875c2
("brd: remove support for BLKFLSBUF"), so this call is entirely
pointless now.
