Arnd Bergmann cd409d0b83 ksmbd: avoid field overflow warning 
[ Upstream commit 9cedc58bdb ]

clang warns about a possible field overflow in a memcpy:

In file included from fs/smb/server/smb_common.c:7:
include/linux/fortify-string.h:583:4: error: call to '__write_overflow_field' declared with 'warning' attribute: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror,-Wattribute-warning]
                        __write_overflow_field(p_size_field, size);

It appears to interpret the "&out[baselen + 4]" as referring to a single
byte of the character array, while the equivalen "out + baselen + 4" is
seen as an offset into the array.

I don't see that kind of warning elsewhere, so just go with the simple
rework.
