pflash_cfi01: Do not exit() on guest aborting "write to buffer"
When a guest tries to abort "write to buffer" (command 0xE8), we print "PFLASH: Possible BUG - Write block confirm", then exit(1). Letting the guest terminate QEMU is not a good idea. Instead, LOG_UNIMP we screwed up, then reset the device. Macro PFLASH_BUG() is now unused; delete it.
