[PATCH -next] freevxfs: Fix some kernel-doc comments

[Yang Li]

Remove the description of @retp and @filler, and add the description
of @ctx, to silence the warnings:

fs/freevxfs/vxfs_lookup.c:192: warning: Function parameter or member 'ctx' not described in 'vxfs_readdir'
fs/freevxfs/vxfs_lookup.c:192: warning: Excess function parameter 'retp' description in 'vxfs_readdir'
fs/freevxfs/vxfs_lookup.c:192: warning: Excess function parameter 'filler' description in 'vxfs_readdir'
