Subject: [PATCH v2 1/5] staging: rtl8192e: Remove variable SetWirelessMode

The variable SetWirelessMode is set in only one place throughout the
driver. This patch removes the variable and calls the real function
directly instead, eliminating the unnecessary indirection.
Additionally, the removal of the variable aligns with the checkpatch
guidelines by removing the use of CamelCase.

Signed-off-by: Yogesh Hegde <yogi.kernel@...il.com>

v2: Removed the variable and called the function direction instead of
    just renaming the variable as suggested by Greg Kroah-Hartman
    <gregkh@...uxfoundation.org>.
