RDMA/bnxt_re: add DCB dependency
When CONFIG_DCB is disabled, we get a link error:
drivers/infiniband/built-in.o: In function `bnxt_re_setup_qos':
trace.c:(.text+0x155774): undefined reference to `dcb_ieee_getapp_mask'
trace.c:(.text+0x155774): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `dcb_ieee_getapp_mask'
trace.c:(.text+0x155794): undefined reference to `dcb_ieee_getapp_mask'
trace.c:(.text+0x155794): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `dcb_ieee_getapp_mask'
Like the other drivers that use this function, a Kconfig dependency is
the correct fix.
