memsw: handle swapaccount kernel parameter correctly
__setup based kernel command line parameters handlers which are handled in
obsolete_checksetup are provided with the parameter value including =
(more precisely everything right after the parameter name).
This means that the current implementation of swapaccount[=1|0] doesn't
work at all because if there is a value for the parameter then we are
testing for "0" resp. "1" but we are getting "=0" resp. "=1" and if
there is no parameter value we are getting an empty string rather than
NULL.
The original noswapccount parameter, which doesn't care about the value,
works correctly.
