block: Clear BIO_EMULATES_ZONE_APPEND flag on BIO completion

Browse Source 
commit f705d33c2f upstream.

When blk_zone_write_plug_bio_endio() is called for a regular write BIO
used to emulate a zone append operation, that is, a BIO flagged with
BIO_EMULATES_ZONE_APPEND, the BIO operation code is restored to the
original REQ_OP_ZONE_APPEND but the BIO_EMULATES_ZONE_APPEND flag is not
cleared. Clear it to fully return the BIO to its orginal definition.

Fixes: 9b1ce7f0c6 ("block: Implement zone append emulation")
