Subject: [PATCH v2] MIPS: Loongson: Use default CONFIG_FRAME_WARN as 2048 for Loongson64 to fix build warnings

After commit 70b838292bef ("MIPS: Update default config file for
Loongson-3"), CONFIG_VHOST_SCSI and CONFIG_VHOST are set when use
loongson3_defconfig, and then there exists the following two build
warnings related with these two configs:

  CC [M]  drivers/vhost/scsi.o
drivers/vhost/scsi.c: In function ‘vhost_scsi_flush’:
drivers/vhost/scsi.c:1374:1: warning: the frame size of 1040 bytes is larger than 1024 bytes [-Wframe-larger-than=]
  LD [M]  drivers/vhost/vhost_scsi.o
  CC [M]  drivers/vhost/vsock.o
  LD [M]  drivers/vhost/vhost_vsock.o
  CC [M]  drivers/vhost/vhost.o
drivers/vhost/vhost.c: In function ‘log_used’:
drivers/vhost/vhost.c:1896:1: warning: the frame size of 1040 bytes is larger than 1024 bytes [-Wframe-larger-than=]

CONFIG_FRAME_WARN=2048 can fix it, since the default CONFIG_FRAME_WARN
for 64BIT is 2048, just delete the CONFIG_FRAME_WARN line in defconfig.

        int "Warn for stack frames larger than"
        range 0 8192
        default 2048 if GCC_PLUGIN_LATENT_ENTROPY
        default 1280 if (!64BIT && PARISC)
        default 1024 if (!64BIT && !PARISC)
        default 2048 if 64BIT
