[PATCH] p54: fix wmm queue settings

[Chr]

This patch fixes a regression (introduced by 453fae72b2f19
"p54: more definitions form lmac_longbow.h and pda.h" )

It turned out that the "ret" variable wasn't initialized and
this caused the following warnings/errors to appear:

wmaster1: failed to set TX queue parameters for queue 2
wmaster1: failed to set TX queue parameters for queue 3
wmaster1: failed to set TX queue parameters for queue 1
wmaster1: failed to set TX queue parameters for queue 0
