[Linux-kernel-mentees] [PATCH v4 2/3] lspci: Remove unnecessary !verbose check in show_range()

[Kelsey Skunberg]

Remove 'if (!verbose)' code in show_range() due to not being called.
show_range() will only be called when verbose is true. Additional call
to check for verbosity within show_range() is dead code.

!verbose was used so nothing would print if the range behind a bridge
had a base > limit and verbose == false. Since show_range() will not be
called when verbose == false, not printing bridge information is
still accomplished.
