[PATCH] wan: wanxl: remove redundant assignment to stat

From: Colin King <hidden>

stat set to zero and the value is never read, instead stat is
set again in the do-loop. Hence the setting to zero is redundant
and can be removed. Cleans up clang warning:

drivers/net/wan/wanxl.c:737:2: warning: Value stored to 'stat'
is never read

it is std. practice to have the pattern:
 a=b;
 if (a == c) ...
maybe that can be done also here.
 stat = readl(card->plx + PLX_MAILBOX_5);
 if ( stat != 0)

just a hint.
