man.vim: avoid duplicate buffers, E95

Browse Source 
Before this commit, man#init_pager() always tries to scrape the manpage
name and set the buffer name. That's much less important than avoiding
duplicate buffers and E95. And it doesn't seem to be necessary, usually.

Steps to reproduce:

    $ export MANPAGER="nvim -c 'set ft=man' -"
    $ man sleep
    :Man sleep

    Error detected while processing function man#init_pager:
    line   15:
    E95: Buffer with this name already exists

    :ls!
    1  h-  "man://SLEEP(1)"               line 4
    2 %a-  "man://sleep(1)"               line 1
