drm/msm: Remove redundant check for 'submit'
Rectify the below smatch warning:
drivers/gpu/drm/msm/msm_gem_submit.c:963 msm_ioctl_gem_submit() warn:
variable dereferenced before check 'submit'
'submit' is normally error pointer or valid, so remove its NULL
initializer as it's confusing and also remove a redundant check for it's
value.
