The rf_set_sens variable is declared but never set, so it is always NULL.
Cleanup the unused rf_set_sens variable. Remove functions
_rtl92e_wx_get_sens and _rtl92e_wx_set_sens which always returned
error code after removal of rf_set_sens variable.
Cleanup unused max_sens and sens variable.
The patches are required to be applied in sequence.

2. Removed usage of variable priv->rf_set_sens
3. Removed functions _rtl92e_wx_get_sens and _rtl92e_wx_set_sens
4. Cleaned up the variables sens and max_sens used in these functions

Changes in v1:
1. Fix comparison to NULL of variable rf_set_sens

Subject: [PATCH v5 1/4] staging: rtl8192e: Remove unused rf_set_sens variable

The rf_set_sens variable is declared but never set, so it is always NULL.
This commit cleans up the unused rf_set_sens variable and removes the
associated code that relied on it.

Specifically, the following changes have been made:
- Removed the `range->sensitivity` assignment, which was never used.
- Removed the sensitivity level get implementation, which always returns
an error code.
- Removed the sensitivity level set implementation, which always returns
an error code.
- Removed the `rf_set_sens` variable.
