[OpenAFS] Documentation for `afsd` argument `files_per_subdir` is wrong (out of sync with the implementation)

Hello all!

I'm using OpenAFS on OpenSUSE, version 1.8.x (in fact 1.8.0 and 1.8.2
on two nodes), and although the documentation for the `afsd` daemon
states for `files_per_subdir` that:
files_per_subdir -- Limits the number of cache files in each
subdirectory of the cache directory. The value of the option should be
the base-two log of the number of cache files per cache subdirectory
(so 10 for 1024 files, 14 for 16384 files, and so forth).

It is in fact use without the exponential transformation.  I.e.
setting `-files_per_subdir 10` will actually result in exactly 10
files per directory, meanwhile `-files_per_subdir 1024` would
correctly result in 1K files.
