Subject: [PATCH 4.2.y-ckt 104/305] net: mvneta: fix bit assignment in MVNETA_RXQ_CONFIG_REG

4.2.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

From: Marcin Wojtas <mw@...ihalf.com>

commit e5bdf689d32fcf3aaf548c71e715b303ba20b5d1 upstream.

MVNETA_RXQ_HW_BUF_ALLOC bit which controls enabling hardware buffer
allocation was mistakenly set as BIT(1). This commit fixes the assignment.
