[PATCH 2/2] procfs.c: Increasing array size

[Andrey Shumilin <shum.sdl@nppct.ru>]

The maximum size in bytes of the port->base and port->base_hi
variables is 20 bytes per variable, since they are copied in
decimal notation. Two more characters are \t and \n.
A maximum of 42 bytes can be written to a buffer variable.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
