[PATCH] rename member variable count to disabled in struct

[Ryan Bradetich]

In a previous email:
http://marc.theaimsgroup.com/?l=linux-kernel&m=100710086202226&w=2

I asked about the possibility of renaming the member variable count to
disabled in the struct tasklet_struct.  I didn't get any responses to my
question so I thought I'd try asking the question a different way :)

This patch does not make any functional changes to the kernel, but I do
believe it makes the tasklet code more readable.

I have tested this against the 2.4.16 kernel.

Thanks,

- Ryan
