[PATCH v2 2/2] misc: pci_endpoint_test: remove dead BAR read before doorbell trigger

[Carlos Bilbao (Lambda)]

From: Carlos Bilbao <carlos.bilbao@xxxxxxxxxx>

The assignment before the writel sequence is dead code (bar is
unconditionally overwritten by the re-read immediately after) so remove the
call entirely.

Note that the DB_BAR register is a plain value written by the endpoint
firmware; reading it carries no side effect.
