staging: wilc1000: remove use of unnecessary 'wilc_connected_ssid' variable

'wilc_connected_ssid' actually used to store the BSSID information for
connected BSSID. 'wilc_vif' already has 'bssid' variable to store the
same information. So refactor code to remove 'wilc_connected_ssid' and
instead used 'wilc_vif' struct 'bssid' element.

staging: erofs: code cleanup for option parsing of fault_injection

Define a dummpy function of erofs_build_fault_attr() when macro
CONFIG_EROFS_FAULT_INJECTION is disabled, so that we don't have to
check the macro in calling place. Based on above adjustment,
do proper code cleanup for option parsing of fault_injection.

staging: erofs: add some comments for xattr subsystem

As Dan Carpenter pointed out, it is better to document what
return values of these callbacks in `struct xattr_iter_handlers'
mean and why it->ofs is increased regardless of success or
failure in `xattr_foreach'.
