[git commit] i2cdump: don't use common_bufsiz1

[Denys Vlasenko]

commit: https://git.busybox.net/busybox/commit/?id=59f81976249a85cf02bd73c2395f018033069466
branch: https://git.busybox.net/busybox/commit/?id=refs/heads/master

Commit e6a2f4cc changed the way common_bufsiz1 works. Now it needs to
be initialized before using, but i2cdump wasn't updated by said patch.

Since the fact that we're using common_bufsiz1 here isn't obvious (no
G_INIT() macro, no other global variables), drop it and simply
allocate the integer array required for block reads on the stack.

Tested with i2c block read on a Lenovo Thinkpad laptop.
