linux/blktap2: reduce TLB flush scope

c/s 885 added very coarse TLB flushing. Since these flushes always
follow single page updates, single page flushes (when available) are
sufficient.

20 This adds an extra check when data is written to the flash. The
21 OneNAND flash device internally checks only bits transitioning
22 from 1 to 0. There is a rare possibility that even though the
23 device thinks the write was successful, a bit could have been
24 flipped accidentaly due to device wear or something else.

36 One Block of the NAND Flash Array memory is reserved as
37 a One-Time Programmable Block memory area.
38 Also, 1st Block of NAND Flash Array can be used as OTP.
40 The OTP block can be read, programmed and locked using the same
41 operations as any other NAND Flash Array memory block.
42 OTP block cannot be erased.
44 OTP block is fully-guaranteed to be a valid block.
