ipc/util.c: further variable name cleanups
The varable names got a mess, thus standardize them again:
id: user space id. Called semid, shmid, msgid if the type is known.
Most functions use "id" already.
idx: "index" for the idr lookup
Right now, some functions use lid, ipc_addid() already uses idx as
the variable name.
seq: sequence number, to avoid quick collisions of the user space id
key: user space key, used for the rhash tree
