virtiofsd: Changed allocations of iovec to GLib's functions

Replaced the calls to malloc()/calloc() and their respective
calls to free() of iovec structs with GLib's allocation and
deallocation functions and used g_autofree when appropriate.

Replaced the allocation of in_sg_cpy to g_new() instead of a call
to calloc() and a null-checking assertion. Not g_new0()
because the buffer is immediately overwritten using memcpy.
