[PATCH -next] spi: mxic: add missing braces

[Yang Yingliang]

Fix the following waring:

drivers/spi/spi-mxic.c: In function ‘mxic_spi_mem_exec_op’:
drivers/spi/spi-mxic.c:401:3: warning: this ‘if’ clause does not guard... [-Wmisleading-indentation]
   if (op->data.dir == SPI_MEM_DATA_IN)
   ^~
drivers/spi/spi-mxic.c:403:4: note: ...this statement, but the latter is misleadingly indented as if it were guarded by the ‘if’
    if (op->data.dtr)
    ^~
