netfs: Renumber the NETFS_RREQ_* flags to make traces easier to read
Renumber the NETFS_RREQ_* flags to put the most useful status bits in the
bottom nibble - and therefore the last hex digit in the trace output -
making it easier to grasp the state at a glance.
In particular, put the IN_PROGRESS flag in bit 0 and ALL_QUEUED at bit 1.
Also make the flags field in /proc/fs/netfs/requests larger to accommodate
all the flags.
Also make the flags field in the netfs_sreq tracepoint larger to
accommodate all the NETFS_SREQ_* flags.
