dma-buf/udmabuf: Fix NULL pointer dereference in udmabuf_create
There is a potential execution path in which pointer memfd is NULL when
passed as argument to fput(), hence there is a NULL pointer dereference
in fput().
Fix this by null checking *memfd* before calling fput().
Addresses-Coverity-ID: 1473174 ("Explicit null dereferenced")
Fixes: fbb0de795078 ("Add udmabuf misc device")
