Subject: [PATCH] staging: wimax/i2400m: don't change the endianness of one
 byte variable

It is wrong to change the endianness of a variable which has just one
byte size.

Sparse warnings fixed:
drivers/staging//wimax/i2400m/control.c:452:17: warning: cast to restricted __le32
drivers/staging//wimax/i2400m/control.c:452:17: warning: cast to restricted __le32
drivers/staging//wimax/i2400m/op-rfkill.c:159:14: warning: cast to restricted __le32
drivers/staging//wimax/i2400m/op-rfkill.c:160:14: warning: cast to restricted __le32
