The msg variable in the fm10k_mbx_validate_msg_size and fm10k_sm_mbx_transmit functions is only used within the do {} loop scope. Reduce its scope only to where it is used. This was detected by cppcheck, and resolves the following warnings produced by that tool: [fm10k_mbx.c:299]: (style) The scope of the variable 'msg' can be reduced. [fm10k_mbx.c:2004]: (style) The scope of the variable 'msg' can be reduced.
