staging: rtl8723bs: fix if-statement alignment and line continuation in rtw_ap.c

This patch fixes several style issues in a multiline if-statement:

- Moved '&&' to the end of the previous line to follow logical continuation style
- Fixed indentation to align with the opening parenthesis of the expression
- Avoided ending a line with an open parenthesis '('
- Moved closing ')' to the end of the last expression line (as suggested by the maintainer)

These changes improve readability and conform to Linux kernel coding conventions.
No functional changes.
