Gustavo A. R. Silva 305325688f NTB/msi: Use struct_size() helper in devm_kzalloc() ...

Make use of the struct_size() helper instead of an open-coded version,
in order to avoid any potential type mistakes or integer overflows that,
in the worst scenario, could lead to heap overflows.

Also, address the following sparse warnings:
drivers/ntb/msi.c:46:23: warning: using sizeof on a flexible structure
