Subject: [PATCH] staging: rtl8723bs: core: Refactor nested if-else

Refactor nested if else by combining nested if into a single if condition and removing unnecessary else conditionals which leads to removing unnecessary tabs .There is no change in logic of new code.
checkpatch warning : Too many leading tabs - consider code refactoring
