container_of() will never return NULL, so remove useless code.

Remove explicit u16 cast of the function Mk16 return value.
The variable hi does not need to be casted explicitly to u16 as it will
already be casted implicitly.

The explicit u16 cast is not necessary because rtl92e_eeprom_read's
second parameter is defined to be u32.

Remove the explicit u16 casts for u16 argument in the function call. This
function has declared its parameter to be of type u16, so the argument
given to that parameter will be automatically coerced to u16. Therefore,
an explicit cast is unnecessary.

Remove the explicit casts in assignment statements for u16 variables.
Because these variables are declared as u16, there is implicit
conversion to u16 during the assignment, so an explicit cast is
unnecessary.

Since the macro VERSION_8190_BD is defined to be 0x3, and the structure
members card_8192_version and IC_Cut are both u8, an explicit u8 cast is
unnecessary.

The rtllib_rx_assoc_resp() function has a signedness bug because it's
a declared as a u16 but it return -ENOMEM.  When you look at it more
closely it returns a mix of error codes including 0xcafe, -ENOMEM, and
a->status which is WLAN_STATUS_NOT_SUPPORTED_AUTH_ALG.  This is a mess.

Clean it up to just return standard kernel error codes.  We can print
out the a->status before returning a regular error code.  The printks
in the caller need to be adjusted as well.

This patch addresses the checkpatch.pl flag that there should not be a
space after a cast.
