Move job memory allocation to v3d_job_init function. This aim to facilitate
error handling in job initialization, since cleanup steps are similar for all
(struct v3d_job)-based types of job involved in a command submission. To
generalize v3d_job_init(), this change takes into account that all job structs
have the first element a struct v3d_job (bin, render, tfu, csd) or it is a
v3d_job itself (clean_job) for pointer casting.
