RDMA/core: Do not allow alloc_commit to fail
This is a left over from an earlier version that creates a lot of complexity for error unwind, particularly for FD uobjects. The only reason this was done is so that anon_inode_get_file() could be called with the final fops and a fully setup uobject. Both need to be setup since unwinding anon_inode_get_file() via fput will call the driver's release(). Now that the driver does not provide release, we no longer need to worry about this complicated sequence, simply create the struct file at the start and allow the core code's release function to deal with the abort case. This allows all the confusing error paths around commit to be removed.
