[PATCH][next] drm/nouveau/fifo/gk104: remove redundant variable ret

[Colin Ian King]

The variable ret is being assigned a value but it isn't being
read afterwards. The assignment is redundant and so ret can be
removed.

Cleans up clang scan build warning:
warning: Although the value stored to 'ret' is used in the enclosing
expression, the value is never actually read from 'ret'
