proc: rearrange args
Rearrange args for smaller code.
lookup revolves around memcmp() which gets len 3rd arg, so propagate
length as 3rd arg.
readdir and lookup add additional arg to VFS ->readdir and ->lookup, so
better add it to the end.
Space savings on x86_64:
add/remove: 0/0 grow/shrink: 0/2 up/down: 0/-18 (-18)
Function old new delta
proc_readdir 22 13 -9
proc_lookup 18 9 -9
proc_match() is smaller if not inlined, I promise!
