DFU mesh light example face ERROR_BUSY (134)

[badidearock]

I have merged Light and DFU examples(Light_DFU), and test DFU update both blinky and Light_DFU.

It is always getting ERROR_BUSY (134) while update Light_DFU, but success with blinky zip.

RTT log:

I am using 52840, SDK: s140_v7.0.1.

Attached is all image and zip files in case you want to reproduce.

ERROR_BUSY (134) is from mesh_flash_in_progress().

Shall we just skip this and try again till progress is done?

Why Blinky one has no issue?
