[SRU][B][PATCH 0/1] Fix BUG scheduling while atomic in tg3 ethernet driver

[Luke Nowakowski-Krijger]

BugLink: https://bugs.launchpad.net/bugs/1995870

[Impact]

There were BUG: scheduling while atomic: ip/1210/0x00000200 appearing
on xenial/hwe with the tg3 ethernet driver when running on rumford instance. 
Probably some performace degradation as the driver was trying to sleep while
holding a spinlock.
There also was cluttering of the kernel log with stack traces.

[Fix]

Change usleep_range -> udelay which is safe to call from atomic
contexts.

[Test]

Compile tested only. Should see this resolved in the next cycle on
xenial/hwe rumford instance.

[Where problems could occur]

Not much regression potential as the correct delay call is now being
called.
