[PATCH] staging: rtl8723bs: replace kmalloc + memcpy with kmemdup in ioctl_cfg80211.c

[Tomasz Unger]

Replace kmalloc() followed by memcpy() with kmemdup() which combines
both operations into a single call, making the code cleaner and more
readable. The zeroing done by kzalloc() is unnecessary here as the
entire buffer is immediately overwritten by memcpy().
