Subject: [PATCH] iwlwifi: mvm: Fix bitwise vs logical operator in iwl_mvm_scan_fits()

Clang warns:

drivers/net/wireless/intel/iwlwifi/mvm/scan.c:835:3: warning: bitwise
and of boolean expressions; did you mean logical and?
[-Wbool-operation-and]
                (n_channels <= mvm->fw->ucode_capa.n_scan_channels) &
                ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                                                                    &&
1 warning generated.

Replace the bitwise AND with a logical one to solve the warning, which
is clearly what was intended.
