[Peter Zijlstra]

drivers/gpu/drm/i915/i915_gem_execbuffer.o: warning: objtool: 
.altinstr_replacement+0x3c: redundant UACCESS disable
drivers/gpu/drm/i915/i915_gem_execbuffer.o: warning: objtool: 
.altinstr_replacement+0x66: redundant UACCESS disable

AKA. you don't need user_access_end() if user_access_begin() fails.
