[spice-server PATCH v1 2/12] migration_protocol: fix alignment warnings on _MAGIC

[Victor Toso <victortoso@xxxxxxxxxx>]

from clang:
inputs_channel.c:274:36: error: cast from 'const char *' to 'uint32_t *'
(aka 'unsigned int *') increases required alignment from 1 to 4
[-Werror,-Wcast-align]
    spice_marshaller_add_uint32(m, SPICE_MIGRATE_DATA_INPUTS_MAGIC);
                                   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
