smb: client: memcpy() with surrounding object base address
[ Upstream commit f69b0187f8745a7a9584f6b13f5e792594b88b2e ]
Like commit f1f047bd7ce0 ("smb: client: Fix -Wstringop-overflow issues"),
adjust the memcpy() destination address to be based off the surrounding
object rather than based off the 4-byte "Protocol" member. This avoids a
build-time warning when compiling under CONFIG_FORTIFY_SOURCE with GCC 15:
In function 'fortify_memcpy_chk',
inlined from 'CIFSSMBSetPathInfo' at ../fs/smb/client/cifssmb.c:5358:2:
../include/linux/fortify-string.h:571:25: error: call to '__write_overflow_field' declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror=attribute-warning]
571 | __write_overflow_field(p_size_field, size);
