firmware: arm_ffa: Avoid string-fortify warning in export_uuid()
Copying to a 16 byte structure into an 8-byte struct member
causes a compile-time warning:
| In file included from drivers/firmware/arm_ffa/driver.c:25:
| In function 'fortify_memcpy_chk',
| inlined from 'export_uuid' at include/linux/uuid.h:88:2,
| inlined from 'ffa_msg_send_direct_req2' at drivers/firmware/arm_ffa/driver.c:488:2:
| 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]
| __write_overflow_field(p_size_field, size);
Use a union for the conversion instead and make sure the byte order
is fixed in the process.
