[PATCH] staging: rtl8723bs: os_intfs: replace msleep with usleep_range

[Connor Sample <tabulatejarl8@gmail.com>]

checkpatch.pl warns that `msleep()` of durations <20ms may sleep for up
to 20ms. As per `Documentation/timers/delay_sleep_functions.rst`,
`usleep_range()` should be used whenever the accuracy of `msleep()` is
not sufficient in order to avoid jiffy rounding.

Replaced `msleep(10)` with `usleep_range(10000, 11000)` and replaced a
1ms polling loop (`msleep(1)`) with `usleep_range(1000, 2000)`. This
should provide improved scheduling tolerances without changing the
minimum delay expectation for the hardware.
