[PATCH 1/4] Char: mxser_new, kill unneeded memsets

[Jiri Slaby]

mxser_new, kill unneeded memsets

There is no need to re-zero static global variables' memory, hence memsets
doing this are useless.
alloc_tty_struct also zeroes allocated memory: another candidate for
removing.
This fixes also a bug -- global structures are cleaned up after
initialization of some its parts.
