fs: fat: Fix mkcksum() function parameters
The mkcksum() function now takes one parameter, the pointer to 11-byte wide character array, which it then operates on. Currently, the function is wrongly passed (dir_entry)->name, which is only 8-byte wide character array. Though by further inspecting the dir_entry structure, it can be noticed that the name[8] entry is immediatelly followed by ext[3] entry. Thus, name[8] and ext[3] in the dir_entry structure actually work as this 11-byte wide array since they're placed right next to each other by current compiler behavior. Depending on this is obviously wrong, thus fix this by correctly passing both (dir_entry)->name and (dir_entry)->ext to the mkcksum() function and adjust the function appropriately.
