mtd: devices: m25p80: Use spi_mem_set_drvdata() instead of spi_set_drvdata() 

SPI mem drivers should use spi_mem_set_drvdata() not spi_set_drvdata()
to store their private data. Using spi_set_drvdata() will mess the
spi -> spi-mem link up and cause a kernel panic at shutdown or
device removal time.

Fixes: 4120f8d158 ("mtd: spi-nor: Use the spi_mem_xx() API")
